DESCRIPTION: Water and ice surfaces and interfaces are ubiquitous\, not jus
 t in nature\, but also in many technological applications. Water is a rath
 er unique liquid\, owing to its strong intermolecular interactions: strong
  hydrogen bonds hold water molecules together. At the surface of water and
  ice\, the water hydrogen-bonded network is abruptly interrupted\, conferr
 ing distinct properties on the interface\, compared to bulk. I will presen
 t some challenges (“how can we study the ~1 monolayer of water molecules
  that is in direct contact with the other phase\, and distinguish this ~An
 gstrom-thin layer from the bulk?”) and progress in the study of interfac
 ial water. I will specifically address the interaction of water with charg
 ed interfaces\, and attempt to explain why ice is slippery.\nSpeaker: Misc

DESCRIPTION:The surprising insulating and superconducting states of narrow-
 band graphene twisted bilayers have been mostly discussed so far in terms 
 of strong electron correlation\, with little or no attention to phonons an
 d electron-phonon effects. We found that\, among the 33492 phonons of a fu
 lly relaxed 1.08° twisted bilayer\, there are few special\, hard\, and ne
 arly dispersionless modes that resemble global vibrations of the moiré su
 percell ('moirè phonons').\nSpeaker: Mattia Angeli

DESCRIPTION: The normal state of unconventional superconductors often exhib
 its anomalous transport properties and it is commonly referred to as a “
 bad” or “strange” metal. Understanding its collective charge dynamic
 s\, which defies the standard quasiparticle description of a Fermi liquid\
 , is an outstanding challenge of modern condensed matter physics.In this t
 alk\, I will present a direct measurement of the collective charge dynamic
 s of the strange metal using inelastic electron scattering. First\, I will
  discuss how normal-state Bi2Sr2CaCu2O8+d is defined by a featureless\, lo
 calized continuum\, undergoing a low-temperature massive spectral weight r
 edistribution. I will then describe how such a phase is found to coexist w
 ith a low-energy Fermi liquid in Sr2RuO4.These results indicate that stran
 ge metals are highly localized in space and dissipate on ultrafast timesca
 les\, seemingly bound only by quantum limits. Implications for the occurre
 nce of high-temperature superconductivity will be discussed.\nSpeaker: Mat

DESCRIPTION:Nonlinear optics (NLO) is one of the most fascinating fields of
  modern physics. It deals with light-matter interactions at extreme electr
 o-magnetic field strengths. Such fields are today routinely available than
 ks to laser technology. NLO started with the observation of second harmoni
 c generation from a ruby laser in 1961\, just 1 year after the first laser
  was operated. It allows producing optical pulses with durations in the fe
 mtosecond (fs\, 10<sup>-15</sup> s) and even attosecond (as\, 10<sup>-18</
 sup> s) order. With such sources\, one can observe chemical reactions\, ph
 ysical and biological phenomena in real time. During the lectures\, I will
  give a short overview of NLO. I will discuss the main physical phenomena 
 (second harmonic generation\, optical parametric amplification\, differenc
 e and sum frequency generation\, white light generation\, third harmonic g
 eneration\, high harmonic generation…) and some of their applications\, 
 and conclude with the newest trends of research like coherent pulse synthe
 sis.\nSpeaker: Giovanni Cirmi

DESCRIPTION: Water is the most important liquid for life. It is intimately 
 linked to our well-being. Without water\, cell membranes cannot function. 
 Charges and charged groups cannot be dissolved\, self-assembly cannot occu
 r\, and proteins cannot fold. Apart from the intimate link with life\, wat
 er also shapes the earth and our climate. Our landscape is formed by slow 
 eroding/dissolving processes of rocks in river and sea water\; aerosols an
 d rain drops provide a means of transport of water. Because of the complex
 ity of liquid water and aqueous interfaces\, the relationship between the 
 unique properties of water and its molecular structure has not been solved

DESCRIPTION:Strong electronic correlations are a main driver behind many ex
 citing phenomena in quantum many-body systems\, ranging from correlated qu
 antum materials (Mott transition\, high-temperature superconductivity) to 
 cold atoms in optical lattices. However\, the strong-correlation problem s
 till poses many challenges when it comes to a quantitative and even qualit
 ative understanding of the relevant degrees of freedom and microscopic int
 eractions that drive phase transitions in solids. Dynamical mean-field the
 ory (DMFT)\, first developed in the late 1980s and 1990s\, provides one ke
 y limit in which the correlation problem becomes tractable\, namely the on
 e of large spatial dimensions\, or local self-energies. In this focus cour
 se we will discuss the basics behind DMFT and learn how this allows one to
  understand the paradigmatic Mott metal-to-insulator transition.\nSpeaker:

DESCRIPTION:Green's functions represent one of the most useful tools for th
 e theoretical description of correlated lattice electrons. In particular\,
  the one-particle Green's function contains information about the spectral
  properties of the system and can be directly compared to (angular resolve
 d) photoemission spectroscopy experiments. However\, also two-particle cor
 relations functions provide very interesting insights into the properties 
 of correlated electron systems as they contain crucial information on resp
 onse functions such as the magnetic susceptibility or the optical conducti
 vity. In my talk\, I will present an overview about the physical content a
 s well as the applications of two-particle Green's and vertex functions in
  frontier condensed matter research. In particular\, I will demonstrate ho
 w local frequency-dependent vertices can be used to include non-local corr
 elations effects in interacting many-electron systems on top of the local 
 ones of dynamical mean-field theory (DMFT). While these so-called diagramm
 atic extensions [1] of DMFT have been successfully exploited to describe c
 ollective phenomena such as magnetism and superconductivity\, their predic
 tive power is still limited by specific inconsistencies between the one- a
 nd the two-particle level [2]. In the final part of my talk\, I will prese
 nt possible solutions to these problems [3] which I will address in the fr
 amework of my Emmy Noether project at the University of Hamburg.\nSpeaker:

DESCRIPTION: Since it’s discovery in 2006\, Graphene has known no rivals 
 in terms of number of applications that scientists from all over the globe
  have thought for him\, ranging from spintronics to energy storage\, from 
 transistors to bio-compatible devices. However\, what’s still hindering 
 his big step from laboratories to industry is a cost-effective method to s
 ynthesize large-scale good-quality crystals. Over the past decade\, great 
 improvements have been made in this direction\, and CVD consolidated as an
  excellent candidate for this arduous task. Among other methods\, a novel 
 technique consisting in the synthesis of crystals on transition metals in 
 the liquid phase has proven to overcome many difficulties related to defec
 t-inducing dislocations and low-diffusivity of solid substrates. Neverthel
 ess\, a clear physical insight over the processes involved during graphene
  nucleation and growth is still lacking\, and many of its parameters are d
 erived by post-process analyses\, neglecting those crucial intermediate st
 eps that may conceal key-factors involved in the process. The reason for t
 his trend is that it’s technically difficult to combine different experi
 mental set-ups\, and an ad-hoc design is more than ever needed to conduct 
 a complete and satisfying investigation. This is the reason behind the LMC
 at project\, that developed a reactor suitable both for CVD growth at high
  temperature by hydrocarbon decomposition and for in-situ Raman and optica
 l studies\, in order to follow in real time the growth of graphene flakes 
 and\, at the same time\, determine its physical properties. Additionally\,
  it aims to prove X-ray techniques\, such as GID and XRR\, as an efficient
  tool for high temperature characterization\, a feat never achieved before
 . This is the framework of this thesis work\, which can of course cover it
  only partially and at a rather early stage. The focus has been put on the
  surprising high contrast showed by radiative optical microscopy at high t
 emperatures (∼ 1100 C°) and on the first\, surprising results coming fr
 om X-ray analysis. The former has been proven as an effective tool for fol
 lowing the growth and derive kinematical parameters\, the latter as a pote
 ntial tool for quantitatively estimate its crystal structure at conditions
  prohibitive for standard probes.\nSpeaker: Sebastian Fava

DESCRIPTION:To understand the function of condensed matter\, it would be de
 sirable to directly watch its atomistic building blocks dynamically intera
 ct on their intrinsic length and time scales. Recently\, lightwave electro
 nics has made this long-standing dream come true. The idea is to exploit t
 he carrier wave of light as an ultrafast\, contact-free bias to interrogat
 e and control the nanocosm. I will first review how lightwaves can drive e
 lectrons in solids into surprising sub-cycle quantum motion. By combining 
 this idea with the sub-angstrom spatial resolution of scanning tunnelling 
 microscopy we can set an ultrashort time window for single-electron tunnel
 ling into a single orbital and record first atom-scale slow-motion movies 
 of individual vibrating molecules. Finally\, I will show how to directly e
 xert femtosecond atomic forces\, which can selectively choreograph a coher
 ent structural motion of a single-molecule switch in its electronic ground
  state. This stunningly direct access to the atomistic world may tailor ke
 y elementary dynamics in nature and steer (bio)chemical reactions or ultra
 fast phase transitions\, on their intrinsic spatio-temporal scales.\nSpeak

DESCRIPTION:Driven-dissipative systems represent natural platforms to study
  non-equilibrium phases. In the first part of the talk\, I will present so
 me physical results for which both non-equilibrium conditions and interact
 ions are crucial. I will argue that a prototype model of correlated driven
 -dissipative lattice bosons\, relevant for upcoming generation of circuit 
 QED arrays experiments\, exhibits a phase transition where a finite freque
 ncy mode becomes unstable\, as an effect of quantum interactions and non-e
 quilibrium conditions. In the broken-symmetry phase the corresponding macr
 oscopic order parameter becomes non-stationary and oscillates in time with
 out damping\, thus breaking continuous time-translational symmetry. To get
  some more insights on this transition\, I studied the spectral properties
  of Markovian driven-dissipative quantum systems using a Lehmann represent
 ation. Focusing on the nonlinear quantum Van der Pol oscillator as a parad
 igmatic example\, I showed that a sign constraint of spectral functions\, 
 which is mathematically exact for closed systems\, gets relaxed for open s
 ystems\; it is eventually replaced by an interplay between dissipation and
  interactions. In the last part of the talk\, I will finally discuss a new
  method to solve quantum impurity models\, small interacting quantum syste
 ms coupled to a non-Markovian environment\, in presence of additional Mark
 ovian dissipation. I will derive a Dyson equation for the time-evolution o
 perator of the reduced density matrix and approximate its self-energy resu
 ming only non-crossing diagrams. I will test this approach on a simple pro
 blem of a fermionic impurity.\nSpeaker: Orazio Scarlatella

  ultrashort laser pulse with solids\, there are two aspects that should be
  considered: the strong electric field of the light pulse induces nonlinea
 r electron dynamics in solids\, and the nonlinear polarization that arises
  from the electron dynamics affects the propagation of the light pulse.\nS

DESCRIPTION: In rare earth intermetallics with weakly bound f-electrons and
  a Kondo energy scale much larger than magnetic exchange interactions or c
 rystal field splittings\, the screening of local moments may result in a n
 on-magnetic Fermi liquid ground state [1]. At low temperatures\, the quant
 um fluctuations between magnetic and non-magnetic valence configurations c
 an then acquire a cooperative (lattice) character. On a phenomenological b
 asis\, a sound understanding of this Anderson Lattice phenomenon has been 
 achieved. On the other hand\, the microscopic description of the coherent 
 coupling between Kondo-screened sites remains an outstanding theoretical c
 hallenge [2]. In experiment\, the cooperative character of Anderson Lattic
 es has only recently become directly accessible. Momentum-resolved spectro
 scopies\, such as angle-resolved photoemission and inelastic neutron scatt
 ering\, reveal the emergence of characteristic low-energy quasiparticle dy
 namics at low temperatures [3]. These methods probe single-particle excita
 tions in the charge and magnetic channels\, respectively. By contrast\, hi
 gh-resolution resonant inelastic x-ray scattering (RIXS) experiments coupl
 e to both charge and spin degrees of freedom in a non-trivial way and thus
  provide a more subtle point of view. If calculations of the underlying Kr
 amers-Heisenberg term on a basis of strongly correlated f-electronic bands
  are achieved\, RIXS may unlock unprecedented microscopic insights into th
 e entanglement of local and itinerant charge and magnetic degrees of freed
 om. This would address a fundamental mechanism of quantum matter\, with re
 levance far beyond lanthanides and actinides. I will review previous spect
 roscopic investigations of intermediate valence materials\, present our re
 cent RIXS results on the archetypal Anderson Lattice compound CePd3\, and 
 highlight some ideas for future x-ray scattering studies at 3rd and 4th ge
 neration light sources.\nSpeaker: Marein Rahn

DESCRIPTION: Lasers have captured scientific interest since their inception
  and increase in the on-target intensity has resulted in powerful petawatt
  (≈1015W) laser systems across the globe [1]. Such a laser gives the pos
 sibility to study and optimize processes such as electron [2] or ion [3] a
 cceleration resulting from interaction of extreme electric fields (E ≥ 0
 .5 TV/m) with matter 0. In this talk\, I would outline the current efforts
  of POLARIS (a Petawatt laser system) in Jena to study the effects of such
  laser-plasma interaction. A single-shot all optical probing was performed
  with Aluminum targets to fully characterize the plasma evolution. The bas
 ic motivation of the work\, the experimental setup used and some results w
 ould be presented in the talk.\nSpeaker: Faran Irshad

DESCRIPTION:We investigate ground state properties of electronic materials 
 strongly coupled to cavity fields. In a two-dimensional electron gas\, we 
 explore electron paring mediated by vacuum fluctuations of the transverse 
 electromagnetic field. To date\, these interactions have only been discuss
 ed in free space\, where their impact is restricted to extremely low tempe
 ratures. We argue that the sub-wavelength confinement of the light field i
 n nanoplasmonic cavities can enhance the induced interaction to an experim
 entally accessible regime. In a one-dimensional Hubbard model\, the cavity
  further enhances magnetic couplings at half-filling\, and introduces next
 -nearest-neighbor hopping. References: F. Schlawin\, A. Cavalleri\, and D.
