Non-equilibrium Fermi Polarons in Driven-Dissipative Systems
Offered By: Erwin Schrödinger International Institute for Mathematics and Physics (ESI) via YouTube
Course Description
Overview
Explore the fascinating world of non-equilibrium Fermi polarons in driven-dissipative systems through this 19-minute conference talk delivered at the Workshop on "Blackbody Radiation Induced Effects and Phenomena" held at the Erwin Schrödinger International Institute for Mathematics and Physics (ESI). Delve into the paradigmatic problem of mobile impurities immersed in degenerate Fermi systems and the formation of quasi-particles called polarons. Discover recent observations of these quasi-particles in ultracold atomic gases and two-dimensional monolayer semiconductors. Learn about the limitations of equilibrium quantum field theory and wave function techniques in describing polaron physics in non-equilibrium systems. Gain insights into a novel approach to non-equilibrium polaron physics based on non-equilibrium quantum field theory. Understand the derivation of a kinetic equation that incorporates dissipation and drive, enabling the study of polaron relaxation and non-equilibrium distributions. Explore the implications of this approach in the context of two-dimensional materials, including the transition towards a lasing regime due to the bosonic nature of polarons and the reduction of emission linewidth below the bare linewidth.
