Nonequilibrium dynamics of quantum umpurities: from resonant Xray scattering in solids to ultracold atoms
Many new experimental techniques in condensed matter physics go beyond the paradigm of linear response measurements. I will use example of resonant Xray scattering in high Tc cuprates to demonstrate how new insights into experimental results can be gained by considering their nonequilibrium aspects. I will also discuss on-going experiments with ultracold atoms that explore quantum dynamics of impurities. Examples include RF spectroscopy and Ramsey interferometry of heavy atoms inside Fermi systems, Rydberg molecular spectroscopy, BEC polarons.
