Abstract

A master equation containing a nonlinear term that gives rise to disentanglement has been recently explored. Here, a modified version, which is applicable for indistinguishable particles, is proposed, and studied 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.

无差别粒子的自发解缠
最近,人们对一个包含非线性项的主方程进行了探索,该方程会导致不纠缠。这里提出了一个适用于不可分粒子的修正版本,并对玻色-哈伯德模型和费米-哈伯德模型进行了研究。研究发现,对于玻色子和费米子,不纠缠都能引起量子相变。
