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
