Abstract

In this work we study a quench between a Mott insulator and a repulsive Lieb-Liniger liquid. We explicitly find the stationary state when a long time has passed after the quench. It is given by a generalized Gibbs ensemble (GGE) density matrix, which we completely characterize, calculating the quasiparticle density that describes the system after the quench. In the long-time limit we find an explicit form for the local three-body density-density-density correlation function and the asymptotic long-distance limit of the two-point density-density correlation function. The latter is shown to have Gaussian decay at large distances.
