Abstract

In this study, we find that if we have a Bose-Einstein condensate (BEC) trapped in an optical lattice interacting with a bath composed of another BEC, and if the system itself is initially in an entangled state, then this initial state keeps the average number of particles in each lattice site and the linear entropy throughout lattice constant through time. This implies that the dissipative effect of the coupling with the bath of excitations facilitates the quantum transport of particles and entanglement in an optical lattice.
