Stationary entanglement entropies following an interaction quench in 1D Bose gas
Stationary entanglement entropies following an interaction quench in 1D Bose gas
We analyze the entanglement properties of the asymptotic steady state after a quench from free to hard-core bosons in one dimension. The Rényi and von Neumann entanglement entropies are found to be extensive, and the latter coincides with the thermodynamic entropy of the generalized Gibbs ensemble (GGE). Computing the spectrum …
