Relaxation and thermalization in the one-dimensional Bose-Hubbard model: A case study for the interaction quantum quench from the atomic limit
Motivated by recent experiments, we study the relaxation dynamics and thermalization in the
one-dimensional Bose-Hubbard model induced by a global interaction quench. Specifically …

On conservation laws, relaxation and pre-relaxation after a quantum quench
M Fagotti - Journal of Statistical Mechanics: Theory and …, 2014 - iopscience.iop.org
We consider the time evolution following a quantum quench in spin-1/2 chains. It is well
known that local conservation laws constrain the dynamics and, eventually, the stationary …

Dynamical manifestations of quantum chaos: correlation hole and bulge
A main feature of a chaotic quantum system is a rigid spectrum where the levels do not
cross. We discuss how the presence of level repulsion in lattice many-body quantum …
