Quantum Coherence and Vortex Control in Optically Imprinted Polariton Landscapes

Explore a 59-minute physics lecture where Prof. Marc Aßmann from Technical University of Dortmund delves into the fascinating world of exciton-polaritons and their quantum properties. Learn about these unique light-matter quasiparticles formed in semiconductor microcavities and how they create macroscopically coherent non-equilibrium condensates at high temperatures. Discover the principles of superfluidity and quantized vortices in solid state physics, along with techniques for investigating polariton condensate properties through spectroscopic methods. Gain insights into the creation and control of quantized vortices using optically imprinted potential landscapes, and understand the quantitative methods for measuring quantum coherence through real-time spectroscopy. Master the concepts of photon correlations and density matrices of light fields while exploring groundbreaking research in polaritonics, supported by significant scientific publications from Nature, Nature Physics, and PRX Quantum.
