Timescales for thermalization and many-body quantum chaos — •Lea Santos — University of Connecticut, Storrs, CT, USA
The timescale for isolated many-body quantum systems to reach thermal equilibrium after a dynamical quench remains an important open question.*We examine how the equilibration process depends on the models, observables, energy of the initial state, and system size, revealing distinct dynamical behaviors across different timescales.*Special attention is given to the dynamical manifestations of many-body quantum chaos and methods for detecting them in experimental setups, such as cold atoms, ion traps, and NMR systems. We show that coupling the system to a dephasing environment can reduce dynamical fluctuations that might otherwise obscure these manifestations.
