Query: Thermalization and prethermalization in isolated quantum systems: a
  theoretical overview   The approach to thermal equilibrium, or thermalization, in isolated quantum
systems is among the most fundamental problems in statistical physics. Recent
theoretical studies have revealed that thermalization in isolated quantum
systems has several remarkable features, which emerge from quantum entanglement
and are quite distinct from those in classical systems. Experimentally, well
isolated and highly controllable ultracold quantum gases offer an ideal system
to study the nonequilibrium dynamics in isolated quantum systems, triggering
intensive recent theoretical endeavors on this fundamental subject. Besides
thermalization, many isolated quantum systems show intriguing behavior in
relaxation processes, especially prethermalization. Prethermalization occurs
when there is a clear separation in relevant time scales and has several
different physical origins depending on individual systems. In this review, we
overview theoretical approaches to the problems of thermalization and
prethermalization.
