DESCRIPTION:Coherent Multi-Dimensional Spectroscopy (CMDS) is a powerful te
 chnique that is directly sensitive to couplings between quantum states. In
  the optical regime\, the technique is well-suited to investigate interact
 ions between the electronic degrees of freedom in systems such as biologic
 al light-harvesting complexes and nanostructures. Following a general intr
 oduction on Multi-Dimensional Spectroscopy\, I will present an ultrafast o
 ptical two-dimensional spectrometer based on a hollow-core fiber for broad
 band visible continuum generation and two acousto-optic pulse shapers arra
 nged in a Mach-Zehnder interferometer for the production of fully-coherent
  pulse trains. The setup can easily switch between a pump-probe geometry a
 nd a collinear geometry with polarization shaping capabilities. The method
 ological improvements presented here represent important enabling steps to
 wards the longstanding goal of achieving an ”Optical NMR”\, and extend
 s the realm of all-optical Multi-Dimensional Spectroscopy to spatially het
 erogeneous samples. The methods developed are then applied on two classes 
 of systems. The model system Nile Blue is used to validate the performance
  of the instrument. The spectrometer is also used to reveal new processes 
 in colloidal semiconductor CdSe nanocrystals. One of the most fascinating 
 aspects of semiconductor nanocrystals is their ability to host multiple ex
 citations per particle. When multiple excitons are created in the same nan
 ocrystal\, bound quasi-particles called multiexcitons form. In contrast to
  the single exciton\, the structural and dynamic properties of multiexcito
 ns remains\, to this day\, relatively poorly understood due to their compl
 exity. In the last part of the seminar\, I will discuss new insights gaine
 d on the structure of the ground state biexciton thanks to the optical CMD
 S method.

DESCRIPTION: Investigation of the ultrafast photoexcited electronic respons
 e in semiconductors has provided invaluable insights into carrier dynamics
 . Germanium and its alloys with Si have promise for creating multi-junctio
 n solar cells with higher efficiency and mid-infrared optoelectronics. How
 ever\, the dynamics are complicated by multiple energetically similar vall
 eys\, rendering an understanding of carrier thermalization and population 
 inversion following photoexcitation difficult. Attosecond transient absorp
 tion spectroscopy (ATAS) has recently been employed to probe ultrafast ele
 ctron and hole dynamics in germanium at the M<sub>4\,5</sub>-edge (~30 eV)
 . In the experiment\, a 5 fs VIS-NIR pump pulse excites carriers across th
 e direct band gap and the dynamics are probed with a time-delayed broadban
 d extreme ultraviolet pulse generated by high harmonic generation in xenon
  spanning ~20-45 eV. The observed transient absorption signal contains the
  energetic distribution of both carriers\, electrons and holes\, due to st
 ate blocking as well as spectroscopic features induced by bandshifts (e.g.
  due to band gap renormalization) and broadening (e.g. due to many body ef
 fects). By iterative procedures the measured signal can be successfully de
 coupled into these contributions resolving the carrier and band dynamics w
 ith excellent time and energy resolution. Hot carrier relaxation on a 100-
 fs time scale and carrier recombination on a 1-ps time scale are observed 
 in nanocrystalline Germanium. Going from bulk semiconductor to two-dimensi
 onal layers\, long-lived core-exciton states are observed at the MoN<sub>2
 \,3</sub> edge between 32 and 35 eV in MoS<sub>2</sub>. Comparing the XUV 
 absorption spectra of bulk and monolayer MoS<sub>2</sub>\, a ~4 eV red-shi
 ft suggests a tightly bound core-exciton. The lifetime of the core-exciton
  states can be directly measured in the time domain. Furthermore\, transie
 nt Stark shifts\, coherences\, and coherent population transfer between di
 fferent core-exciton states are observed.\nSpeaker: Michael Zürch

DESCRIPTION: Graphene is a key reduced dimensionality solid with many promi
 sing applications. Its spectroscopy is vital to understanding the quantum 
 physics of graphene and to evaluate some of the potential uses of graphene
 . We have found that new and very different interpretations of graphene sp
 ectroscopy and ultrafast pump-probe experiments are required. This will be
  explained. They are very informative about the role of phonon assisted pr
 ocesses in solids and the role of the electronic transition matrix element

DESCRIPTION:The prospect of “forcing” the formation of quantum coherent
  states in matter\, by means of pulsed electromagnetic fields\, discloses 
 a new regime of physics where thermodynamic limits can be bridged and quan
 tum effects can\, in principle\, appear at ambient temperatures. In this p
 resentation I will introduce the field of optical control of correlated el
 ectron systems. I will focus on the possibility of coherently driving low-
 lying excitations of quantum many body systems making light-based control 
 of quantum phases in real materials feasible. I will review the recent res
 ults in archetypal strongly correlated cuprate superconductors and introdu
 ce our new approach to go beyond mean photon number observables. I will sh
 ow that quantum features of light can provide a richer statistical informa
 tion than standard linear and non-linear optical spectroscopies. This will
  potentially uncover with unprecedented detail the evolution and propertie
 s of light-induced transient states of matter.ReferencesScience 331 (6014)

DESCRIPTION:Multidimensional spectroscopy uses sequences of optical pulses 
 to study dynamical processes in complex molecules through correlation plot
 s involving several time delay periods. Extensions of these techniques to 
 the x-ray regime will be discussed. Ultrafast nonlinear x-ray spectroscopy
  is made possible by newly developed free electron laser and high harmonic
  generation sources. The attosecond duration of X-ray pulses and the atomi
 c selectivity of core X-ray excitations offer a uniquely high spatial and 
 temporal resolution. Stimulated Raman detection of an X-ray probe may be u
 sed to monitor the phase and dynamics of nonequilibrium valence electronic
  state wavepackets created by e.g. photoexcitation\, photoionization and A
 uger processes. Novel ultrafast X ray probes for strongly coupled electron
 -nuclear dynamics \, techniques based on a coherent stimulated Raman proce
 ss that employs a composite femtosecond/attosecond X-ray pulse to directly
  detect the electronic coherences (rather than populations) \, and new ima
 ging techniques based on x-ray diffraction from electronic coherence will 
 be presented. Nonlinear optical signals induced by quantized light fields 
 and entangled photon pairs are presented. Conventional nonlinear spectrosc
 opy uses classical light to detect matter properties through the variation
  of its response with frequencies or time delays. Quantum light opens up n
 ew avenues for spectroscopy by utilizing parameters of the quantum state o
 f light as novel control knobs and through the variation of photon statist
 ics by coupling to matter. Entangled-photon pairs are not subjected to the
  classical Fourier limitations on the joint temporal and spectral resoluti
 on. Strong coupling of molecules to the vacuum field of micro cavities can
  modify the potential energy surfaces thereby manipulating the photophysic
 al and photochemical reaction pathways. Crossings of electronic potential 
 surfaces in nuclear configuration space\, known as conical intersections\,
  determine the rates and outcomes of virtually all photochemical molecular
  processes. Strong coupling of molecules to the quantum vacuum field of mi
 cro cavities that can be used to manipulate their photophysical and photoc
 hemical reaction pathways and polariton relaxation in photosynthetic anten
 nae are demonstrated.\nSpeaker: Shaul Mukamel

DESCRIPTION:Two challenges in the simulation of excitation energy transfer 
 and optical spectra of pigment-protein complexes are the equal magnitude o
 f the excitonic and the exciton-vibrational coupling and the structure-bas
 ed parametrization of the Hamiltonian (for review see ref. 1). We have dev
 eloped quantum chemical/electrostatics/normal mode analysis (NMA) schemes 
 to calculate optical transition energies of pigments in their binding site
  in the protein (site energies)\, interpigment excitonic couplings and the
  spectral density of the pigment-protein coupling. Our NMA of the spectral
  density shows that the modulation of site energies is an order of magnitu
 de stronger than that of the excitonic couplings and that also in the basi
 s of delocalized exciton states the diagonal exciton-vibrational coupling 
 dominates [2]. This result explains the good performance of our earlier ti
 me-local lineshape theory [3]\, in which the diagonal elements are treated
  exactly and the off-diagonal elements in Markov and secular approximation
 s\, and triggered a new development that takes into account the finite rel
 axation time of nuclei during exciton relaxation [4]. I will give a summar
 y of our theory development and present applications on a small model syst
 em (water soluble chlorophyll binding protein -WSCP) and large photosystem
  II core particles. In the case of WSCP we have developed and applied a th
 eory of holeburning spectroscopy [5] that goes beyond the standard two-lev
 el system approach and allows for a quantitative description of experiment
 al data\, revealing the lifetime of the upper exciton state\, in excellent
  agreement with results from 2D electronic spectroscopy and our earlier pr
 ediction [6]. In the case of photosystem II I will present results of the 
 parametrization of the exciton Hamiltonian of its subunits [7-9]. These pa
 rameters were used to describe VIS/IR pump-probe data on single crystals o
 f PSII core particles [10] that allowed for a verification of our earlier 
 prediction [11] on the relative timescale of excitation energy and charge 
 transfer in this system. The results are discussed in terms of photoprotec
 tion scenarios that allow photosystem II to switch between a light harvest
 ing and an excitation energy quenching mode protecting the reaction center

 e from the topologically nontrivial state characterized by the Chern numbe
 r. How these properties are affected and manifest in the presence time-dep
 endent perturbations is still a sparsely explored field of research. This 
 applies\,in particular\, to quantum quenches between topologically distinc
 t phases. Identifying robust measures of topology which are applicable in 
 nonequilibrium scenarios — ideally also for correlated materials or diss
 ipative systems — is thus a nontrivial task.\nSpeaker: Michael Schüler

DESCRIPTION:Putting materials out of equilibrium can produce new quantum ph
 enomena. When driven by a circularly-polarised laser\, a massless Dirac sy
 stem such as graphene can be converted into the Floquet topological insula
 tor of photon-dressed electrons\, which realises the quantum anomalous Hal
 l effect. The phase diagram becomes increasingly intricate for lower laser
  frequencies where transitions between different Chern numbers take place.
  If we consider electron correlation\, we can predict transitions between 
 Floquet topological insulators and Mott insulator[1]. In another avenue a 
 linearlypolarised light can induce the collective Higgs amplitude mode in 
 superconductors\, a condensed-matter analogue of the renowned particle. Th
 en a resonantly strong third-harmonic generation arises\, where the Higgs 
 mode contribution is shown to dominate[2] unlike in the BCS approximation.

DESCRIPTION:To a large extent\, our knowledge of the photoinduced dynamics 
 of molecular systems at the atomic level is shaped by nonlinear femtosecon
 d spectroscopy. Traditionally\, nonlinear femtosecond spectroscopy is an e
 nsemble spectroscopy\, performed on ensembles of identical chromophores in
  the gas phase or in the liquid phase. Modern femtosecond spectroscopy com
 prises a set of various third-order or higher-order technique including\, 
 for example\, fluorescence up conversion\, transient absorption\, and phot
 on echo spectroscopy. Very recently\, the portfolio of femtosecond techniq
 ues has been extended towards singlemolecule detection by the development 
 of fluorescence-detected double-pump singlemolecule spectroscopy. With thi
 s technique\, a temporal resolution of about ten femtoseconds has been ach
 ieved. The technique permits the real-time monitoring of not only electron
 ic populations\, but also of electronic and vibrational coherence for indi
 vidual molecules.\nSpeaker: Lipeng Chen

DESCRIPTION: Water is the most common liquid. Its properties are not\, howe
 ver\, common. Since the anomalies of water become pronounced at low temper
 atures\, especially below its melting temperature\, it has been proposed t
 hat the anomalous properties are attributed to the presence of two liquid 
 states corresponding to the two amorphous ices. Experimental studies of su
 percooled water are however very difficult. This is due to the fact that b
 ulk water is easily transferred to a crystalline phase in the “no man’
 s land”\, which is a temperature range bounded by the crystallization of
  supercooled water at ~235K and by that of highly viscous liquid water at 
 ~150K. Therefore\, various theoretical and computational studies have been
  conducted for understanding the properties in the no man’s land. We hav
 e performed extensive molecular dynamics simulations from normal liquid to
  deeply supercooled states to reveal the structural and dynamical instabil
 ities in the no man’s land. The spatiotemporal fluctuations\, dynamic tr
 ansition\, glass transition\, and vibrational contribution to Kauzmann tem
 perature of supercooled water will be discussed.\nSpeaker: Shinji Saito

DESCRIPTION:Ultrafast optical spectroscopy of quantum materials uncovers th
 eir intrinsic physical properties such as light-matter interactions and dy
 namics of particles and quasi-particles. In this presentation\, I will pre
 sent our ultrafast optical studies of two different electronic systems: to
 pological insulators (TIs) and two-dimensional transition metal Dichalcoge
 nides (2D TMDs). In TIs\, where Dirac-like topological surface states (TSS
 s) coexist with an underlying bulk insulator\, we have investigated ultraf
 ast dynamics of TSS Dirac fermions and plasmons\, and their interactions w
 ith phonon by using optical-pump terahertz-probe spectroscopy. We have fou
 nd that\, unlike Dirac electrons in graphene\, TSS Dirac electrons exhibit
  unique dynamic features originating from interactions with coexisting bul
 k insulator. In the studies of 2D TMDs\, we have performed ultrafast optic
 al pump-probe spectroscopy of anisotropic excitons in group-VII TMDs. We d
 iscuss coherent light-matter interactions such as excitonic optical Stark 
 effect and quantum beats\, both of which exhibit significant laser-polariz
 ation dependence\, resulting from anisotropic nature of the excitons.\nSpe

DESCRIPTION:This project is based on the study of signals which ANTARES neu
 trino telescope have detected between 2007 and 2015. Firstly\, an introduc
 tion about the sources of neutrinos and what we know about the origins of 
 cosmic neutrinos is showed. Then\, It will be explained the process of det
 ection of neutrinos used by ANTARES neutrino telescope. Secondly\, the ana
 lysis of the detected data in the 9 years mentioned before is carried out.
  The first part of the analysis consists in a comparison between detected 
 data and simulated data will be shown for some variables\, like neutrino d
 irection or energy of them. The Monte Carlo simulated data is done in orde
 r to reproduce the observed Background and reduce it by applying cut-offs.
  Also the simulation of the expected signals from cosmic neutrinos is done
  to compare to the fitted background. The second part consists in the sear
 ch of the cut-offs which will help to improve the signal/noise ratio. Thes
 e cut-offs will be selected by mean of the analysis of some parameters or 
 applying statistical methods\, like Feldmann-Cousin method. Finally\, the 
 obtained signal is showed to extract conclusions.\nSpeaker: Pedro de la To

DESCRIPTION: Whenever a small-scale system is weakly coupled to macroscopic
  and Markovian reservoirs\, it is possible to establish a consistent therm
 odynamic framework -- even for systems far away from equilibrium and even 
 at the level of single\, fluctuating trajectories. But outside the Markovi
 an and weak coupling regime already the definition of basic quantities suc
 h as internal energy or heat becomes problematic. After reviewing the phen
 omenology of non-equilibrium thermodynamics\, I will discuss a technique w
 hich allows to map a strongly coupled\, non-Markovian system to a weakly c
 oupled\, Markovian one by appropriately including environmental degrees of
  freedom in the description of the system. Thus\, by redefining the system
 -environment partition\, it is possible to carry over a consistent thermod
 ynamic framework to the strong coupling situation.\nSpeaker: Philipp Stras

DESCRIPTION: In my talk I will discuss this question: How can density funct
 ional and tensor network theory be combined in such a way that they benefi
 t from each other. In particular I will present our publication [1] in whi
 ch we developed a systematic procedure for the approximation of density fu
 nctionals in density functional theory that consists of two parts. In the 
 first part\, for the efficient approximation of a general density function
 al\, we introduced an efficient ansatz whose non-locality can be increased
  systematically. In the second part\, we presented a fitting strategy that
  is based on systematically increasing a reasonably chosen set of training
  densities. I will present our results from reference [1] for strongly cor
 related fermions on a one-dimensional lattice. In this context we focused 
 on the exchange-correlation energy and demonstrated how an efficient appro
 ximation can be found that includes and systematically improves beyond the
  local density approximation. Remarkably\, we could show this systematic i
 mprovement for target densities that are quite different from the training
  densities. [1] M. Lubasch\, J. I. Fuks\, H. Appel\, A. Rubio\, J. I. Cira

DESCRIPTION: Topological insulators and superconductors are characterized b
 y their gapless boundary modes. In this talk\, we develop a recursive appr
 oach to the boundary Green function which encodes this nontrivial boundary
  physics. Our approach describes the various topologically trivial and non
 trivial phases as fixed points of a recursion and provides direct access t
 o the phase diagram\, the localization properties of the edge modes\, as w
 ell as topological indices. We illustrate our approach in the context of v
 arious familiar models such as the Su-Schrieffer-Heeger model\, the Kitaev
  chain\, and a model for a Chern insulator. We also show that the method p
 rovides an intuitive approach to understand recently introduced topologica
 l phases which exhibit gapless corner states. Ref: Yang Peng\, Yimu Bao\,

DESCRIPTION: Advances in light sources and time resolved spectroscopy have 
 made it possible to excite specific atomic vibrations in solids and to obs
 erve the resulting changes in electronic properties but the mechanism by w
 hich phonon excitation causes qualitative changes in electronic properties
 \, has remained unclear. Here we show that the dominant symmetry-allowed c
 oupling between electron density and dipole active modes implies an electr
 on density-dependent squeezing of the phonon state which provides an attra
 ctive contribution to the electron-electron interaction\, independent of t
 he sign of the bare electron-phonon coupling and with a magnitude proporti
 onal to the degree of laser-induced phonon excitation. Reasonable excitati
 on amplitudes lead to non-negligible attractive interactions that may caus
 e significant transient changes in electronic properties including superco
 nductivity. The mechanism is generically applicable to a wide range of sys
 tems\, offering a promising route to manipulating and controlling electron
 ic phase behavior in novel materials.\nSpeaker: Dante Kennes

DESCRIPTION: In this talk\, I will present some of the results in my PhD di
 ssertation\, whose main topic is the geometric description of open quantum
  systems. Differential geometry allows for an intrinsic formulation of mat
 hematical models\, thus achieving a better characterisation of their prope
 rties. I will analyse from a geometric perspective the manifold of pure an
 d mixed states of quantum systems and its properties\, such as its stratif
 ication in terms of the rank of states [1]. The algebraic properties of ob
 servables allow to define a Poisson and a symmetric tensor fields on the m
 anifold\, which are necessary in order to describe features such as dissip
 ation and Markovian dynamics in an intrinsic way. Applications to Molecula
 r Dynamics\, in particular the Hamiltonian description of the Ehrenfest mo
 del\, will also be discussed [2\,3]. [1] Grabowski\, Kus\, Marmo. Symmetri

DESCRIPTION: Strong laser beams allow for the coherent control of electrons
 \, as for example electron diffraction in standing light waves [1]. In my 
 talk I will discuss the possible manipulation of the electron spin in X-ra
 y diffraction\, in which the interacting standing wave of light can be for
 med from intensive and coherent X-ray beams from free-electron lasers [2].
  The quantum dynamics of this process is theoretically modeled by insertin
 g a plane wave ansatz for the electro-magnetic field and the electron wave
  function into the Dirac equation [3]. Based on this relativistic quantum 
 description and substantiated by numeric and analytic solutions I will tal
 k about the necessary kinematic conditions for generating spin effects in 
 light-matter interaction. To the end I will present spin dynamics in circu
 larly polarized laser fields [4\,5] and discuss how circular polarization 
 can be used for generating spin-dependent diffraction and spin polarizatio

DESCRIPTION: The electronic and optical properties of a material critically
  depend on its defects\, and understanding that requires substantial and a
 ccurate input from theory. Defect calculations in traditional semiconducto
 rs have relied on the local and semi/local approximations of density funct
 ional theory\, which in wide band gap materials may lead to fatal errors. 
 Since first-principle total energy methods beyond these approximations can
 not yet be carried out with sufficient accuracy for the supercells needed 
 in defect calculations\, nowadays semi-empirical hybrid functionals are of
 ten applied instead. In my talk I will analyze the performance of the HSE0
 6 screened hybrid functional on defects in Group-IV semiconductors and in 
 TiO<sub>2</sub>\, and show that its success is the result of error compens
 ation between semi-local and non-local exchange\, resulting in a proper de
 rivative discontinuity (reproduction of the band gap) and a total energy w
 hich is a linear function of the fractional occupation numbers (removing m
 ost of the electron self-interaction). As it is well known\, however\, HSE
 06 does not work equally well for all materials. On the example of Ga<sub>
 2</sub>O<sub>3</sub>\, I will show that tuning both the mixing and the scr
 eening parameter of HSE for the given material allows to ensure the same e
 rror compensation. Unless the electronic screening is strongly direction- 
 or orbital-dependent (as in ZnO)\, the optimized HSE hybrid is nearly self
 -interaction free and provides a band structure on par with GW. Since the 
 total energy can also be calculated\, the real equilibrium structure of a 
 defect can be found and the levels are in good agreement with experimental
  observations.\nSpeaker: Peter Deák

DESCRIPTION:The perovskite iridate Sr<sub>n+1</sub>IrnO<sub>3n+1</sub> real
 izes an interesting analogue to the cuprate high Tc superconductor. When e
 lectron-doped\, the single-layer Sr<sub>2</sub>IrO<sub>4</sub> is shown to
  manifest a pseudogap phase and possibly d-wave superconductivity. Using s
 econd harmonic generation rotational anisotropy\, we show that near the an
 tiferromagnetic transition there exists a magnetic multipolar order that b
 reaks inversion symmetry in hole-doped Sr<sub>2</sub>IrO<sub>4</sub>. One 
 candidate for this order is the loop current order that is predicted to ex
 ist in the pseudogap region of cuprate. In bilayer Sr<sub>3</sub>Ir<sub>2<
 /sub>O<sub>7</sub>\, electron-doping has been found to induce an insulator
 -to-metal transition in addition to a structural phase transition at low t
 emperature. There has been no prior experimental evidence of electronic in
 stabilities in the bilayer system. Using time-resolved optical reflectivit
 y\, we detect a charge-density-wave-like instability in metallic samples o
 f electron-doped Sr<sub>3</sub>Ir<sub>2</sub>O<sub>7</sub>. The absence of
  signatures of a new spatial periodicity from diffraction\, scanning tunne
 lling and photoemission based probes suggests an unconventional and possib
 ly short-ranged nature of this density wave order.\nSpeaker: Hao Chu

DESCRIPTION: The valley degree of freedom and the possibility of spin-valle
 y coupling of solid materials have attracted growing interest\, and the re
 laxation dynamics of spin- and valley-polarized states has become an impor
 tant focus of recent studies. In spin-orbit-coupled inversion-asymmetric t
 wo-dimensional materials\, such as MoS<sub>2</sub>\, it has been found tha
 t the spin randomization is characteristically faster than the time scales
  for inter- and intra-valley scatterings. In this talk\, I present our rec
 ent study of the ultrafast non-collinear spin dynamics of the electron in 
 a valley of monolayer MoS2 by using real-time propagation time-dependent d
 ensity functional theory. We found that the spin precession is sharply sel
 ectively coupled only with the particular optical phonon that lifts the in
 -plane mirror symmetry. We suggest that the observed spin randomization ca
 n be attributed to this spin-phonon interaction. Further\, our results imp
 ly that flipping of spins in a spin-orbit-coupled system can be achieved b
 y the control over phonons. In a later part of the talk\, I would also des
 cribe the feature of the computational package we have developed and have 
 used for the spin-phonon dynamics\, which is based on the plane-wave basis
  set and various types of pseudopotentials.\nSpeaker: Noejung Park

 over the past decade on the efficient coupling of light and single quantum
  emitters\, leading to the single-photon communication of two individual m
 olecules at long distances [1]. In this context\, we will also discuss new
  results on a high-efficiency triggered source of single photons [2] and c
 oherent nonlinear optical phenomena\, which let a single organic molecule 
 act as an efficient switch for weak beams of light [3]. The long-term goal
  of these projects is to establish a platform for nano-quantum-optical ope
 rations and cooperative interactions in a mesoscopic system of photons and
  quantum emitters [4\, 5]. In order to achieve this\, we have developed no
 vel microcavity [6] and chip-based nanoguide circuitry [7] for use at cryo
 genic conditions.References:[1] Y. Rezus\, et al.\, Phys. Rev. Lett. 108\,

DESCRIPTION:In the design of nanocolloids for targeted applications\, wheth
 er the nanoparticles are used as drug delivery vehicles or as filler in na
 nocomposites\, it is crucial to control the stability\, the miscibility an
 d/or the self-assembly of the nanocolloids. In order to gain such control\
 , the surface of the nanocolloid is frequently functionalized by tethering
  a corona of either small molecules or polymer chains. The nature and the 
 composition of the corona formed by the tethered molecules dictate the int
 eractions between the nanocolloids and their environment and thus the fina
 l behavior of the material. Nanoparticles functionalized with a corona of 
 polymer brush were used in the design of hierarchically structured materia
 ls and displayed new collective properties. By varying the degree of polym
 erization\, the grafting density and the chemical composition of the polym
 er chains\, a variety of structures were obtained. We now want to establis
 h a correlation between the mesoscopic properties observed in these nanopa
 rticle-based systems with the properties\, structure and dynamic of the po
 lymer brush layer.\nSpeaker: Dr. Heloise Therien-Aubin

DESCRIPTION: In light of recent experiments suggesting light-induced superc
 onductivity [1] as well as light-enhanced electron-lattice coupling [2] fo
 r strongly driven IR phonons\, it is natural to ask for a minimal and gene
 ric theoretical model that predicts such enhancement effects of important 
 couplings in different material classes. One idea that comes to mind is no
 nlinear electron-phonon coupling [3\,4]. A quadratic coupling term of the 
 form "<i> </i><i>g<sub>2</sub> n<sub>el </sub>x<sup>2</sup><sub>IR</sub></
 i> " is generically the lowest order symmetry-allowed direct coupling of a
 n IR-active phonon coordinate <i>x<sub>IR</sub></i> to the electronic dens
 ity <i>n<sub>el</sub></i> in systems with inversion symmetry. In this talk
  I will present model evidence for light-enhanced electron-phonon coupling
  and light-induced effective attraction between electrons based on nonline
 ar electron-phonon coupling [3]\, the latter of which was already discusse
 d in a similar context in [4]. [1] M. Mitrano et al.\, Nature 530\, 461 (2

 obiological processes are dominated by conical intersections (CIs)\, which

DESCRIPTION: Strongly correlated electron systems driven out of equilibrium
  have attracted much attention because of potential routes to realizing in
 triguing phenomena that are not attainable in the equilibrium. To treat su
 ch systems\, we proposed a time-dependent trial wave function with many va
 riational parameters for the time-dependent variational Monte Carlo method
 . To show the accuracy of our trial wave function in nonequilibrium states
 \, we present our benchmark results for relaxation dynamics during and aft
 er interaction quench protocols of fermionic Hubbard models. We find that 
 our trial wave function well reproduces the exact results for the time evo
 lution of physical quantities such as momentum distribution and supercondu
 cting correlations. As its application\, I will show the dynamics of d-wav
 e superconductivity in two-dimensional correlated electron system under a 
 laser irradiation. Our results show that the superconductivity can be enha
 nced by irradiating strong laser. I will discuss the origins of this enhan
 cement associated with the laser effect and the relation between supercond
 uctivity and charge inhomogeneous phases.\nSpeaker: Kota Ido

DESCRIPTION: Recently it has been shown that using two stages of ion mobili
 ty it is possible to measure isomerizations - structural changes in isolat
 ed molecules. Moreover\, it is possible to measure the relative energies o
 f different isomers and to deduce the barrier energy for each isomerizatio
 n pathway. We have applied the technique to one of the most biologically i
 mportant cases\; that of the retinal protonated Schiff base (RPSB). RPSB i
 s the chromophore which acts as a photon detector in every known form of a
 nimal vision. The primary step in vision is photoisomerization of the RPSB
 \, which then activates the surrounding protein. We have studied the barri
 er energies for isomerizations of the RPSB and have shown them to be signi
 ficantly lower than within the protein. We have also compared different de
 rivatives of the chromophore and shown that slight changes to the structur
 e of the chromophore\, can dramatically effects its energy landscape.\nSpe

DESCRIPTION: Density functional theory in finite basis sets tends to degene
 rate to one-body reduced (1RDM) functional theory. As all calculations are
  done in finite basis sets\, a rigorous foundation of 1RDM functional theo
 ry is desirable. To avoid uniqueness problems in the potential to 1RDM map
 ping\, I will discuss the foundations of 1RDM functional theory in finite 
 basis sets at finite temperatures\, both for fermions and bosons. The ferm
 ionic case turns out to be relatively straightforward\, but the bosonic ca
 se requires more care. The main result is that we can rigorously proof v-r
 epresentability and functional differentiability in this setting.\nSpeaker

DESCRIPTION:The scanning tunneling microscope allows to build and study nan
 ostructures at a single atom level. It can be further used to explore the 
 ballistic electron transport regime by bringing the tip into contact with 
 single atoms and molecules in a well-defined way. The measurement of quant
 um shot noise in nanoscopic contacts provides additional information on th
 e underlying conduction processes and reveals a spin polarization of the c
 urrent by single Fe and Co atoms between two gold electrodes. The impact o
 f spin-orbit coupling on electron transport is demonstrated using single I
 r atoms on a ferromagnetic substrate\, where large changes of the anisotro
 pic magnetoresistance are observed between the tunneling and the contact r
 egime. In ballistic transport through a Mn-porphyrin molecule we demonstra
 te\, that the voltage drop over the molecular junction moves from the tip-
 molecule gap to the molecule-substrate bond for higher conductances. This 
 strongly modifies the shape of the measured Kondo resonance.\nSpeaker: Ale

DESCRIPTION: Under the influence of periodic fields quantum systems may rea
 ch regimes inaccessible under equilibrium conditions and new phases may be
  engineered by a tunable control [1]. The coexistence of periodic driving 
 forces and electron-electron correlation is particularly interesting for t
 wo main reasons: on one side the external driving effectively modulates th
 e inter-site hopping enhancing the effects of the e-e repulsion and the te
 ndency to an insulating behaviour. On the other hand\, irradiation itself 
 is responsible for a photo-doping consisting in an electronic energy dress
 ing that may turn a Mott insulator into a metal. Due to these competing ef
 fects\, novel phenomena are expected when strongly correlated quantum syst
 ems are exposed to time-dependent fields.\nSpeaker: Matteo Puviani

DESCRIPTION:The presentation aims to give a brief review of several theoret
 ical works carried out for layered superconductors [1-4]. It will be shown
  that the dependence of the transmission coefficient of nonlinear THz wave
 s on the incident wave amplitude shows hysteretic behavior both when the w
 aves are propagating along and across superconducting layers. The polariza
 tion transformation of incident waves after their reflection and transmiss
 ion through a layered superconductor can occur. However\, there exist two 
 waves with mutually orthogonal polarizations\, which practically do not in
 teract with each other even in the nonlinear case. Using these two mutuall
 y orthogonal polarizations\, we study polarization transformation of nonli
 near transverse electric and transverse magnetic waves. In addition\, we s
 how that external magnetic field can be effectively used to control transp
 arency and polarization transformation in layered superconductors.\nSpeake

DESCRIPTION: Terahertz (THz) electromagnetic radiation is located in the ga
 p that separates the realms of electronics (&lt\;1 THz) and optics (&gt\;3
 0 THz). Sub-picosecond THz pulses are capable of probing and even controll
 ing numerous low-energy excitations such as phonons\, excitons and Cooper 
 pairs. Here\, we consider experiments showing that THz radiation is also a
  very useful and versatile tool in the fields of spintronics and ultrafast
  magnetism. First\, we optically launch ultrafast spin transport and study
  its conversion into charge currents by means of the inverse spin Hall eff
 ect [Nature Nanotech. 8\, 256 (2013)]. The charge current can be detected 
 by sampling the concomitantly emitted THz radiation. This approach allows 
 us to monitor ultrafast spin currents and provides a quick and easy estima
 te of the strength of the spin Hall effect in a contact-free manner. In ad
 dition\, optimization of the spintronic structure has led to new\, efficie
 nt and scalable emitters of THz pulses that fully cover the range from 1 t
 o 30 THz without gap [Nature Photon. 10\, 483 (2016)]. Second\, we address
  spin-lattice coupling by selective excitation of optical phonons in the m
 odel ferrimagnetic insulator Y<sub>3</sub>Fe<sub>5</sub>O<sub>12</sub> (YI
 G) and find a quenching of magnetic order on a time scale as short as 1 ps
 . This observation attests to a highly efficient coupling of crystal latti
 ce and electron spins in this material.\nSpeaker: Tobias Kampfrath
