SUMMARY:RTG Seminar: Prasana Kumar Sahoo
DESCRIPTION:Engineering excitons in 2D lateral heterostructures for reconfigurable devices\n\n\n\nQuantum Materials & Device Research Lab (QMDrL)\, Materials Science Centre\,Indian Institute of Technology Kharagpur\, India \n\n\n\nTwo-dimensional semiconductor lateral heterostructures (LHS) provide atomically sharp 1D interfaces for controlling charge carriers\, excitons\, and light. I will present scalable growth of seamless TMD LHS\, exhibiting tunable PN junctions\, electroluminescence\, excitonic transistor operation\, and reversible photoconductivity. These materials offer a versatile platform for quantum photonics\, exciton-based devices\, and low-dimensional quantum systems. \n\n\n\nVenue: RUN 0.34

SUMMARY:RTG Seminar: Yiqi Fang
DESCRIPTION:Shaping electron dynamics with structured light\n\n\n\nFAU Erlangen\, Institute of Laser Physics \n\n\n\n \n\n\n\nLaser-excited electron motions allow the investigation of fundamental physical phenomena with unprecedented resolution in time\, space and energy. Structured light offers new opportunities to tailor and control the optical response of materials\, far beyond the ability of conventional linearly or circularly polarized light. In this talk\, I will show the physics and application of structured light when it interacts with bound electrons in atoms as well as when it interacts with electron pulses in free space. \n\n\n\n \n\n\n\n \n\n\n\n \n\n\n\nVenue: RUN.0.35

SUMMARY:RTG Seminar:Martin Švec
DESCRIPTION:Venue: RUN.0.35 \n\n\n\nPhoton-induced processes at single molecules in SPM nanocavities \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\n\n\n\n\n\n\n\n\n\n\nMartin Švec \n\n\n\nInstitute of PhysicsCzech Academy of SciencesPraha 6\,Czech Republic

SUMMARY:RTG Seminar:Patrick Rupprecht
DESCRIPTION:Venue: RUN auditorium 1st floor \n\n\n\nShedding light on ultrafast quantum dynamics with attosecond spectroscopy \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\n\n\n\n\n\n\n\n\n\n\nPatrick Rupprecht \n\n\n\nFeodor Lynen Postdoctoral FellowLeone & Neumark GroupsLawrence Berkeley National LaboratoryUSA
