Evolution of entanglement entropy in strongly correlated bosons in an optical lattice
Evolution of entanglement entropy in strongly correlated bosons in an optical lattice
We investigate the time evolution of the second-order R\'enyi entropy (RE) for bosons in a one-dimensional optical lattice following a sudden quench of the hopping amplitude $J$. Specifically, we examine systems that are quenched into the strongly correlated Mott-insulating (MI) regime with $J/U\ensuremath{\ll}1$ ($U$ denotes the strength of the on-site …
