  A master equation containing a nonlinear term that gives rise to
disentanglement has been recently investigated. In this study, a modified
version, which is applicable for indistinguishable particles, is proposed, and
explored for both the Bose-Hubbard and the Fermi-Hubbard models. It is found
for both Bosons and Fermions that disentanglement can give rise to quantum
phase transitions.
