Equilibration of Isolated Quantum Systems: Timescales and the Role of Locality

Abstract:
Equilibration is a key concept in thermodynamics, and there recently has been renewed interest in deriving equilibration in isolated quantum systems from a microscopic theory. To explain why equilibration is observed in nature, one needs to show that equilibration takes place on physical timescales, neither too long for equilibrium ever to be attained, nor too short for the equilibration process to be observed. After introducing the key concepts of the field, I present a Lieb-Robinson-type bound on equilibration timescales of generic isolated quantum systems.
