DESCRIPTION: Charge density wave (CDW) ordering and the mechanism for it re
 mains a live issue\, particularly in transition-metal dichalcogenide (TMD)
  systems. These are attractive because of both the variety of material pro
 perties they are known to host\, and their conveniently layered van der Wa
 als structures. The evolution of properties and interactions of these mate
 rials when thinned to a monolayer limit remains an area for exploration. I
 n this talk\, I present some background on the study of CDW order in bulk 
 and monolayer TMDs. I then discuss some recent results\, as well as my own
  upcoming investigations of TiTe2\, utilising molecular beam epitaxy (MBE)
  growth and photon energy-dependent angle resolved photoemission spectrosc
 opy (ARPES).\nVortragende(r): Alisa Danilenko

DESCRIPTION:Cell membranes are formed of lipid bilayers\, and separate the 
 interiors of all living cells from the surroundings. They have an integral
  role in maintaining the internal environment of cells. Anaesthetics have 
 been shown to have a potency directly proportional to their affinity for l
 ipid substances\, strongly implying that the effect of anaesthesia is due 
 to the action on cell membranes of the anaesthetic molecules. Previous stu
 dies have demonstrated the effects of anaesthetics on lipid melting points
 \, but no experiments have looked at changes in mechanical properties.\nVo

DESCRIPTION:In recent years\, electron diffraction has arisen as an alterna
 tive to X-ray diffraction for structural studies on threedimensional cryst
 als. Promising features of the technique include complete data sets from a
  few or even singlenanocrystals\, sensitivity to the charged state of ions
  and the relatively low expense of the apparatus. Experimentalprotocols an
 d detector technologies are improving\, so that data collection using the 
 rotation method\, dominant inX-ray crystallography\, is now feasible in a 
 cryoTEM. This convergence of experimental techniques has beenaccompanied b
 y repurposing of analysis tools: robust and sophisticated algorithms devel
 oped over decades forX-ray diffraction integration software can be now emp
 loyed to tackle electron diffraction data. Nevertheless\, thegeometry of t
 he electron diffraction experiment incurs specific challenges to address i
 n the analysis. Here\, thediffraction integration package DIALS is discuss
 ed\, highlighting particular adaptations that were made to thesoftware for
  various example cases of electron diffraction\, particularly on protein c
 rystals. The experience gainedindicates that integration of good quality E
 D data can be straightforward\, but the bottleneck remains with collection
 of such good data\, which relies on careful calibration and understanding 
 of the instrument. Improved apparatus willameliorate this issue and future
  studies to develop improved models for details including dynamic diffract
 ion andabsorption are anticipated.\nVortragende(r): David G. Waterman

DESCRIPTION: The theoretical description of nonlinear optical spectroscopy 
 has traditionally been laid in the framework of perturbation theory. Withi
 n this formalism\, an intuitive approach to the understanding of the dynam
 ics of a molecular system excited by several external laser pulses is base
 d on the concept of nonlinear response functions. However\, as the system 
 complexity increases or nontrivial dynamic effects have to be taken into a
 ccount (nonadiabatic interstate couplings\, bath-induced relaxation) the p
 erturbative approach becomes computationally expensive. To tackle this sce
 nario nonperturbative approaches based on the numerically exact solution o
 f quantum equations of motions have been developed.\nVortragende(r): Elisa

DESCRIPTION:Water\, due to its unique hydrogen bonds\, is one of the materi
 als exhibiting diverse phases\, crystal morphologies\, and phase transform
 ation. As a result of interplay between environmental conditions and molec
 ular kinetics\, more than 25 crystalline and amorphous ices have been repo
 rted with various growing morphologies from polyhedron to needle. Dynamic 
 diamond anvil cell (dDAC)\, which may simply resolve the interference of m
 acroscopic driving force and microscopic kinetics by changing compression 
 rate\, is essential to study complex phase transition behaviour of water. 
 In the present study\, we haveinvestigated the effect of compression rate 
 on crystal growth and the multiple freezing-melting pathways of H2O under 
 far-from-equilibrium condition by using dDAC at room temperature. First\, 
 we reveal the origin of shock growth of ice VI single crystal. Under rapid
  compression (strain rate &gt\; ~0.1 /s)\, we observed a morphological tra
 nsition in ice VI growth from three-dimension (3-d) to twodimension (2-d) 
 with one-order higher growth speed. It is found that local growth conditio
 n and interface kinetics can be affected by compression rate\, which facil
 itate the 2-d shock growth. Secondly\, we explore five different pathways 
 of freezing and melting of deeply supercompressed water and ice via metast
 able phases. We will discuss the mechanism of freezing and melting by calc
 ulating driving force and interfacial free energy based on the classical n
 ucleation theory\, and comparing structure of supercompressed water and st
 able and metastable ices obtained from Raman spectroscopy.\nVortragende(r)

DESCRIPTION:Distinctive superconducting behaviors between bulk and monolaye
 r FeSe make it challenging to obtain a unified picture of all FeSe-based s
 uperconductors. Here\, we investigate the ultrafast quasiparticle dynamics
  of an intercalated superconductor (Li<sub>1-x</sub>Fe<sub>x</sub>)OHFe<su
 b>1-y</sub>Se\, which is a bulk crystal but shares a similar electronic st
 ructure with single-layer FeSe on SrTiO<sub>3</sub>. We obtain the electro
 nphonon coupling (EPC) constant λ (0.24 ± 0.03)\, which well bridges tha
 t of bulk FeSe crystal and single-layer FeSe/SrTiO3 [1]. Moreover\, we fin
 d that such a positive correlation between λ and superconducting T<sub>c<
 /sub> holds among all knownFeSe-based superconductors\, even in line with 
 reported FeAs-based superconductors. Our observation indicates possible un
 iversal role of EPC in the superconductivity of all known categories of ir
 on-based superconductors\, which is a critical step towards achieving a un
 ified superconducting mechanism for all iron-based superconductors.Referen

DESCRIPTION:I will talk about our findings on the theory of ultrafast and u
 ltrastrong optical field interacting with two-dimensional materials with a
 n emphasis on honeycomb-shaped structures such as graphene. In fact\, this
  talk is the emergence of two important and growing branches of science: u
 ltrafast optics and 2D nanocrystals. Ultrafast optics or more specifically
 \, attosecond science\, is developed to study the quantum mechanical dynam
 ics of electrons\, both collective and individual\, on atomic and molecula
 r scales and in high-density mesoscopic systems. Recent advances in attose
 cond metrology and generation of ultrashort optical pulses with just a few
  oscillations of the electric field have provided real-time access to the 
 motion of electrons on atomic and sub-atomic scales and opened a unique po
 ssibility for the coherent control of electron dynamics at sub-femtosecond
  time scale. Hence\, the research and exploration of ultrafast dynamics of
  electrons in novel graphene-like materials under the illumination of few-
 cycle optical fields should prove useful to a growing community of scienti
 sts and hold promises for the future technologies especially high-speed me
 mories\, ultrafast imaging\, and petahertz signal processing.\nVortragende

DESCRIPTION:The nonequilibrium dynamicis of the superconductors has been in
 tensively studied over decades. Among the viriety of nonequlibrium phenome
 na\, the study of the collective dynamics of superconducting order paramet
 er is of essential importance\, as it provides deep insights into the prop
 erties of the order parameter. Recent developments of generating intense e
 lectromagnetic pulses in the terahertz (THz) frequency range have enabled 
 the access to low energy collective modes without giving excess energy to 
 the system. Particularly the amplitude fluctuation of the order parameter\
 , referred to as the Higgs mode\, has been observed in a conventional s-wa
 ve superconductor Nb<sub>1-x</sub>Ti<sub>x</sub>N [1\,2]. Its extension to
  unconventional d-wave superconductors is intriguing\, whereas it has been
  nontrivial whether the Higgs mode in d-wave superconductors is observable
  or not.\nVortragende(r): Kota Katsumi

DESCRIPTION:1T-TaS2 is a layered transition metal dichalcogenide with a ver
 y rich phase diagram\, which was investigated since the early 1970s. At T=
 180K it undergoes a metal to Mott insulator transition. Mott insulators us
 ually display anti-ferromagnetic ordering in the insulating phase but 1T-T
 aS2 was never shown to order magnetically. We have shown that 1T-TaS2 has 
 a large paramagnetic contribution to the magnetic susceptibility but it do
 es not show any sign of magnetic ordering or freezing down to 20mK\, as pr
 obed by muSR\, possibly indicating a quantum spin liquid ground state. Alt
 hough 1T-TaS2 exhibits a strong resistive behavior both in and out of plan
 e at low temperatures we find a linear term in the heat capacity suggestin
 g the existence of a Fermi-surface\, which has an anomalously strong magne
 tic field dependence.\nVortragende(r): Amit Ribak

DESCRIPTION:More than fifty years ago\, it was the invention of the laser t
 hat revolutionized atomic physics and laid the foundations for quantum opt
 ics and coherent control. With only optical frequencies available\, the in
 teraction of coherent light with matter was for a long time mainly restric
 ted to atomic transitions. Only recently have novelhigh-frequency light so
 urces rendered x-ray quantum optics possible. In this higher frequency reg
 ime\, atomic nuclei rise as natural candidates for the interaction with co
 herent light creating a new bridge between atomic physics\, quantum optics
  and nuclear condensed matter physics. Nuclei are very clean quantum syste
 ms\, well isolated from the environment and benefiting from long coherence
  times. Combining the advantages of x-rays and nuclei\, a prominent incent
 ive is to exploit x-rays as the future quantum information carriers or for
  novel probing technologies based on quantum effects. Furthermore\, the co
 ntrol of nuclear transitions would open the possibility to use long-lived 
 nuclear excited states as a compact and clean energy storage solution. The
  lecture will follow the developments on the emerging field of x-ray quant
 um optics and focus on the mutual control of coherent x-ray radiation and 
 nuclear transitions in this new regime of laser-matter interactions.\nVort

 continuously about a circular trajectory has profound implications for on-

DESCRIPTION:Over the recent years\, high-harmonic generation has establishe
 d itself as a promising spectroscopic technique. Notable examples include 
 the tomographic imaging of molecular wave functions [1]\, the tracking of 
 nuclear dynamics [2]\, and the reconstruction of the attosecond time-scale
  electron dynamics in molecules [3\, 4].All these applications\, however\,
  have been limited to laser fields with linear polarization. High harmonic
  generation has only recently been extended to circularly-polarized driver
 s by utilizing a technique known as bi-circular high-harmonic generation (
 BHHG) [5\,6\,7]. In this talk\, I will demonstrate the spectroscopic appli
 cations of this technique to the study of structure and dynamics of gas-ph
 ase atoms and molecules in a self-probing manner. I will start with an ana
 lysis of the helicity asymmetry of BHHG in noble-gas atoms and then procee
 d by illustrating how BHHG can be applied to study dynamical symmetry-brea
 king in a time-dependent manner in the context of rotational and vibration
 al molecular motion.Extension of high-harmonic generation to the regime of
  highly-elliptical fields opens up the way towards the study of chiral phe
 nomena in high-harmonic generation. In this work\, circular dichroism in t
 he range of 3-8 % is observed on randomly oriented methyl oxirane (C3H6O) 
 molecules in the gas phase. This chiral sensitivity is attributed to the s
 ub-cycle chiral electron dynamics involving excited states of the cation t
 hat take place during the electron continuum propagation. Finally\, I will
  present a study of time-dependent chirality based on following the tempor
 al evolution of circular dichroism during the course of an ultrafast photo
 dissociation reaction.\nVortragende(r): Denitsa Baykusheva

DESCRIPTION:Multiferroic materials\, which exhibiting simultaneously two or
  more coupled ferroic orders\, are attracting extensive research interest 
 mainly due to their promising device applications in low power electronics
  and the exotic physics involved. Despite the fact that an increasing numb
 er of multiferroics have been identified through two decades of diligent a
 nd creative studies\, their low transition temperature or small magnetoele
 ctric coupling strength has hindered direct device applications. Searching
  for materials with room-temperature ferroelectricity\, a large enough mag
 netization and coupling between these two is still the Holy Grail for fund
 amental condensed matter research. In this talk\, I will report a novel ro
 om temperature multiferroic in the Bi-Fe-O system. The material is compris
 ed of a hitherto-unexplored\, hexagonal crystalline structure with Bi2O3 l
 ayers separated by γ-Fe<sub>2</sub>O<sub>3</sub> blocks\, which blends th
 e excellent ferroelectric and ferrimagnetic performances of BiFeO<sub>3</s
 ub> and γ-Fe<sub>2</sub>O<sub>3</sub> together to form an exotic multifer
 roic material with ferroelectric and ferrimagnetic transition temperature 
 of above 760 K and 600 K\, respectively. A combination of experimental and
  theoretical studies reveals that the polar state stems from the two dissi
 milar Bi sites and extends further into oxygen ions with the exquisitely m
 odulated structure. This finding identifies a novel strategy for the reali
 zation of high-temperature multiferroicity and paves the pathway for the r
 ealization of practical room temperature magnetoelectric devices.\nVortrag

DESCRIPTION: Transmission electron microscopy (TEM) has traditionally been 
 associated with the study of thin solid samples in vacuum. With the availa
 bility of reliable thin membranes of silicon nitride\, TEM of liquid speci
 mens has become accessible with nanoscale resolution in the past decade [1
 ]. The usage of scanning transmission electron microscopy (STEM) presents 
 a novel concept to study membrane proteins within whole mammalian cells in
  their native liquid environment [2]. The cells in liquid are placed in a 
 microfluidic chamber enclosing the sample in the vacuum of the electron mi
 croscope\, and are then imaged with STEM. It is not always necessary to en
 close the cells in the microfluidic chamber. For many studies\, it is suff
 icient to obtain information from the thin outer regions of the cells\, an
 d those can be imaged with high resolution using environmental scanning el
 ectron microscopy (ESEM) with STEM detector [3]. A third option is to cove
 r a liquid specimen under a thin membrane of graphene providing the thinne
 st possible layer [4]. Liquid STEM was used to explore the formation of HE
 R2 homodimers at the single-molecule level in intact SKBR3 breast cancer c
 ells in liquid state [3]. HER2 is a membrane protein and plays an importan
 t role in breast cancer aggressiveness and progression. Data analysis base
 d on calculating the pair correlation function from individual HER2 positi
 ons revealed remarkable differences its functional state between rare- and
  bulk cancer cells with relevance for studying the role of cancer cell het
 erogeneity in drug response. We discovered a small sub-populations of canc
 er cells with a different response to a prescription drug [5]. Liquid STEM
  was also used to explore the behavior of nanoparticles in liquid in time-
 lapse experiments. It was discovered that nanoparticle movement in close p
 roximity of the supporting silicon nitride membrane was three orders of ma
 gnitude slower than what was expected on the basis of Brownian motion for 
 a bulk liquid [6]\, pointing to the existence of a layer of highly ordered
  liquid at the membrane. References [1] de Jonge\, N. and Ross\, F.M. <i>N
