A well-isolated system often shows a relaxation to a quasi-stationaly state before reaching thermal equilibrium. Such a prethermalization has attracted considerable interest recently in association with closely related fundamental problems of relaxation and thermalization of isolated quantum systems. Motivated by the recent experiment in ultracold atoms, we study the dynamics of a one-dimensional Bose gas which is split into two subsystems, and find that individual subsystems relax to Gibbx states, yet the entire system does not due to quantum entanglement. We investigated Entanglement prethermalization using the Bethe ansatz method.
