SUMMARY:RTG seminar:Martin Švec
DESCRIPTION:Photon-induced processes at single molecules in SPM nanocavitiesInstitute of PhysicsCzech Academy of SciencesPraha 6\,Czech Republic \n\n\n\n \n\n\n\n \n\n\n\nExploration of isolated chromophores – optically active molecules – often reveals stunningly complex internal dynamics of excitations and transitions between electronic configurations\, influenced by coupling to vibrational levels and reorganization of local environments. One of the promising tools for studying the photophysics of individual molecules with nanometer resolution is optical spectroscopy that employs plasmonic\, atomically sharp tips in Scanning Probe Microscopy (SPM)\, which overcomes the fundamental spatial resolution limits of visible and infrared light. This methodology enables measurements that correlate electronic structure and atomic arrangement with various photon spectroscopies – e.g.\, fluorescence\, absorption\, and Raman scattering – as a function of applied electric field and measurement geometry. In this lecture\, I will present our experiments with photon spectroscopies using SPM\, focusing in particular on photon absorption-induced phenomena such as photoluminescence\, and photon-induced current generation\, through which we achieved a direct visual discrimination among the components of a multiconfigurational state of an open-shell chromophore. \n\n\n\nVenue: RUN 0\,35

SUMMARY:RTG Seminar:Dr. Carolin Gold
DESCRIPTION:From microscopic to macroscopic phenomena:Bridging length scales in two- dimensional quantum materials \n\n\n\nColumbia University \n\n\n\nTwo-dimensional quantum materials have driven a revolution in condensed matter physics through the realization of a large variety of exotic quantum phenomena\, ranging from strong correlations and quantum magnetism to topological states. At the core of this revolution is the unique tunability of the quantum phases emergent at the macroscopic scale through variations in the microscopic roperties of the material. Despite decades of intensive theoretical and experimental endeavors\, bridging these two length scales has remained a major challenge\, leaving numerous questions nanswered.In this talk\, we demonstrate how atomic force microscopy (AFM) can be used not only to (i) probe quantum electronic states across multiple length scales\, but also to (ii) locally control and engineer the interplay between microscopic and acroscopic properties in van der Waals materials. Using the AFM tip as a mechanical actuator we bend narrow van der Waals ribbons\, realizing (moiré) heterostructures with engineered twist angle and strain gradients. Combining these structures with low-temperature conductive AFM imaging not only reveals their unique electronic properties\, but also opens exciting avenues for studying the interplay between microscopic and macroscopic length scales through versatile and novel AFM techniques. \n\n\n\n \n\n\n\n \n\n\n\n \n\n\n\nVenue: RUN Auditorium

SUMMARY:RTG Colloquium:Prof. Dr. Miriam Vitiello
DESCRIPTION:Detector-less near-field quantum nanoscopy in the far-infraredNEST\, CNR – Istituto Nanoscienze and Scuola Normale Superiore\, Pisa\, Italy \n\n\n\nNear-field nanoscopy at terahertz (THz) frequencies (wavelength range\, 3 mm – 3 µm) enables studies of objects over a large span of scales – from 300 µm to the nanometer scale – and disciplines\, from physics to biological science. The talk will show the potential of a series of near-field nanoimaging approaches that\, while exploiting the same core building block (a detector-less QCL-based nanoscope)\, rely on different physical mechanism for imaging reconstruction. I will also highlight their potential for tracing the realspace propagation of THz-frequency polaritons in isotropic and anisotropic nanomaterials and meta-elements. \n\n\n\n \n\n\n\n \n\n\n\n \n\n\n\nVenue: RUN Auditorium

SUMMARY:Special lecture: Prof. Dr. Sebastian Loth
DESCRIPTION:Stochastic and coherent dynamics of spins and electrons at the atomic scaleInstitute for Functional Matter and Quantum Technologies\, University of Stuttgart \n\n\n\n \n\n\n\nMany fascinating phenomena at the atomic scale\, such as energy transfer between quantumsystems or collective behavior of electrons in correlated materials\, remain hidden to staticmeasurements. The combination of ultrafast spectroscopy with scanning probe microscopypresents a unique opportunity to study the dynamics of matter locally at its intrinsic length andtime scales. This lecture introduces recent advances using all-electronic microwave spectroscopy to capture quantum dynamics of magnetic atoms and small quantum magnets\, as well as lightcoupled THz pump-probe techniques with femtosecond resolution that reveal phonon propagation and collective excitations in charge-density wave materials. \n\n\n\n \n\n\n\n \n\n\n\nVenue: RUN Auditorium

SUMMARY:RTG Colloquium:Prof. Dr. Jim Freericks
DESCRIPTION:How to describe pump-probe experiments in quantum materialsGeorgetown University\, Washington\, USA \n\n\n\n \n\n\n\nI will describe both the challenges\, and how to address them\, when theoretically modelling ultrafast pump-probe experiments in strongly correlated materials and in materials with strong electron-phonon coupling. After providing an introduction\, I will focus on three case studies: (i) examining the response at picosecond times of charge-density waves with ultrashort pulses that drive the electrons; (ii) examining the response on femtosecond times for nonresonant electronic Raman scattering; and (iii) examining how one can measure correlated charge dynamics in f-electronsystems using x-ray photoemission spectroscopy and x-ray absorption spectroscopy. \n\n\n\n \n\n\n\n \n\n\n\nVenue: H34

SUMMARY:RTG Seminar:Assistant Professor Ipsita Mandal
DESCRIPTION:Detectable signatures of topology of the bandstructures in 3d semimetalsShiv Nadar Institution of Eminence (SNIoE)\, India \n\n\n\n \n\n\n\nWe will elucidate the nature of the linear-response tensors in planar-Hall and planar-thermal-Hall set-ups\, where we subject a 3d semimetal (harbouring nodal points of topological nature) to the combine influence of an electric field (and/or temperature gradient) and a weak (i.e. non-quantising) magnetic field. We will explain why it is essential to include the effects of the intrinsic orbital magnetic moment of the wavepackets in conjunction with the Berry curvature\, in order to obtain a holistic picture of the effects of topology of the Brillouin zone in the linear-response tensors. Going beyond the well-studied example of Weyl semimetals\, we will discuss the cases of their multifold cousins\, harbouring higher Chern numbers. We will highlight how we can compute the exact solutions from the Boltzmann equations\, which gets rid of the often-inaccurate results of the naive relaxation-time approximation. Finally\, we will outline how to derive surface states\, in the form of Fermi arcs\, characterising generic nodal points. \n\n\n\n \n\n\n\nVenue: PHY 5.0.21

SUMMARY:RTG Colloquium: Prof. Dr. Rudolf Bratschitsch
DESCRIPTION:Title: Magnonic waveguide networks \n\n\n\nUltrafast solid-state quantum optics and nanophotonics\, Physical Institute\, University of Münster\, Münster\, Germany \n\n\n\nSpin waves (magnons) have emerged as a promising platform for next-generation physical computing. However\, current experimental realizations of magnonic waveguides suffer from limited spin-wave propagation lengths and inefficient dispersion tuning capabilities. In my talk\, I will present low-loss magnonic waveguides in a thin magnetic insulator film\, fabricated with a new maskless silicon ion implantation technique. We demonstrate a large-scale magnonic network\, paving the way for wafer-scale magnonic integrated circuits. \n\n\n\n \n\n\n\n \n\n\n\nVenue: RUN Auditorium

SUMMARY:RTG Colloquium:Dr. Anna Rosławska
DESCRIPTION:Single-molecule optics with atomic precision\n\n\n\nAtomic Scale Optics\, Max Planck Institute for Solid State Research\, Stuttgart\, Germany \n\n\n\nLuminescence\, photosynthesis\, and energy harvesting rely on processes originating at the spatial scale of individual molecules. Investigating the details of these mechanisms requires reaching subnm precision in optics\, which becomes possible by combining optical spectroscopy with scanningprobe microscopy. In my talk\, I will discuss how atomic-scale optics can be used to study the optical properties of single molecules and to drive photochemistry with sub-nm precision. \n\n\n\n \n\n\n\nVenue: RUN Auditorium

SUMMARY:RTG Colloquium:Prof. Dr. Renske van der Veen
DESCRIPTION:Fast electrons and hard X-rays for unraveling atomic-scale dynamics in light-energy conversion\n\n\n\nDepartment Atomic-Scale Dynamics in Light-Energy Conversion\, Helmholtz Zentrum Berlin \n\n\n\nThe increasing demand for renewable and low-cost energy motivates intensive research aimed at characterizing and optimizing materials that can efficiently convert (sun) light into usable energy in the form of electricity or chemical fuels. Conventional characterization techniques either lack the spatial resolution necessary to resolve individual atoms\, or they lack the temporal resolution required to capture structural rearrangements as they evolve. Our group develops complementary X-ray and electron-based tools to visualize light-induced processes in materials on atomic length and time scales. In this talk I will introduce you to the techniques of ultrafast/time-resolved X-ray spectroscopy and transmission electron microscopy and provide several examples of how these techniques can be used in the fields of solar energy and catalysis. \n\n\n\n \n\n\n\n \n\n\n\n \n\n\n\nVenue: RUN Auditorium
