Description

The central goal of this project is to study the relaxation dynamics of disordered quantum spin systems towards equilibrium after a quantum quench. As model system serves an ensemble of Rydberg atoms where the spin is encoded in two electronically highly excited states. We will develop experimental schemes for measuring unequal-time correlation functions providing access to aging phenomena, probe fluctuation dissipation relations out of equilibrium, and studies of operator spreading or “scrambling”. We will develop effective theoretical descriptions in order to identify the relevant degrees of freedom at long times.
