Lack of thermalization for integrability-breaking impurities
Lack of thermalization for integrability-breaking impurities
We investigate the effects of localized integrability-breaking perturbations on the large times dynamics of thermodynamic one-dimensional quantum and classical systems. In particular, we suddenly activate an impurity which breaks the integrability of an otherwise homogeneous system. We focus on the large times dynamics and on the thermalization properties of the …
