Quantum Equilibration (2011-2013)
Abstract
Equilibrium thermodynamics is a cornerstone of physics. However, describing how isolated quantum systems recover from a disturbance is surprisingly elusive. We will uncover the dynamical mechanisms of equilibration in a variety of ultra-cold quantum systems, and will develop a phenomenological theory for understanding the different classes. Not only is quantum equilibration a fundamental question about the laws of nature, our results will provide practical benefits for the development of quantum simulators. These systems are designed to experimentally solve computationally hard problems in materials science, and it is crucial to understand how and on what timescales they reach thermal equilibrium.
