Thermalization Dynamics of Bi-partite Bose-Hubbard Models Academic Article uri icon

abstract

  • We study the time evolution of a bi-partite Bose-Hubbard model prepared far from equilibrium. When the classical dynamics is chaotic, we observe ergodization of the number distribution and a constant increase of the entanglement entropy between the constituent subsystems until it saturates to thermal equilibrium values. No thermalization is obtained when the system is launched in quasi-integrable phase space regions.
