SUMMARY:RTG Seminar: Ryo Shimano
DESCRIPTION:Higgs mode in superconductors studied by nonlinear terahertz spectroscopy Cryogenic Research Center & Department of Physics \n\n\n\nThe University of Tokio \n\n\n\ng \n\n\n\nRecent developments of experimental techniques based on ultrafast spectroscopy have enabled the access to low energy collective modes in quantum materials in a time-resolved manner. In particular\, the amplitude mode of the order parameter in superconductors\, called the Higgs amplitude mode\, has attracted a growing interest from the viewpoint of non-equilibrium dynamics in symmetry-broken ordered phases. In this presentation\, I will introduce the study of the Higgs mode and other collective modes in conventional and unconventional superconductors using various nonlinear terahertz spectroscopic schemes. \n\n\n\n \n\n\n\nVenue: RUN Auditorium

SUMMARY:RTG seminar: Patrick Rupprecht
DESCRIPTION:Shedding light on ultrafast quantum dynamics with attosecond spectroscopyFeodor Lynen Postdoctoral FellowLeone & Neumark GroupsLawrence Berkeley National LaboratoryUSA \n\n\n\n \n\n\n\nThe physics and chemistry of matter is determined by the interaction of electrons and nuclei on ultrafast timescales down to the attosecond (10-18 s) regime. In this seminar\, I will highlight how attosecond photon spectroscopy grants us a detailed look into the intricate quantum dynamics within atoms and molecules. Beyond precision metrology\, shortest laser pulses allow us to precisely manipulate the quantum interactions of electrons and nuclei. \n\n\n\nVenue: RUN auditorium

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
