Analytic results for a quantum quench from free to hard-core one-dimensional bosons
Analytic results for a quantum quench from free to hard-core one-dimensional bosons
It is widely believed that the stationary properties after a quantum quench in integrable systems can be described by a generalized Gibbs ensemble (GGE), even if all of the analytical evidence is based on free theories in which the pre- and postquench modes are linearly related. In contrast, we consider …
