Thermalization without eigenstate thermalization hypothesis after a quantum quench
Thermalization without eigenstate thermalization hypothesis after a quantum quench
Nonequilibrium dynamics of a nonintegrable system without the eigenstate thermalization hypothesis is studied. It is shown that, in the thermodynamic limit, this model thermalizes after an arbitrary quantum quench at finite temperature, although it does not satisfy the eigenstate thermalization hypothesis. In contrast, when the system size is finite and …
