论文摘要
我们为一类量子驱动的骨值模型的稳态中的稳态提出了一个精确的解决方案，其中一组模式受任意的两光子驾驶，单光子损失和全局Hubbard（或KERR）类似的相互作用。我们的解决方案揭示了许多惊人的现象，包括耗散相变的出现，非平凡模式竞争物理和对称性破坏，以及多体$ SU（1,1）$ PAIP相干状态的稳定。我们的确切解决方案可以描述空间相关性，并且在传统的均值场和半经典方法分解的方案中完全有效。
We present an exact solution in arbitrary dimensions for the steady states of a class of quantum driven-dissipative bosonic models, where a set of modes is subject to arbitrary two-photon driving, single-photon loss and a global Hubbard (or Kerr)-like interaction. Our solutions reveal a wealth of striking phenomena, including the emergence of dissipative phase transitions, nontrivial mode competition physics and symmetry breaking, and the stabilization of many-body $SU(1,1)$ pair coherent states. Our exact solutions enable the description of spatial correlations, and are fully valid in regimes where traditional mean-field and semiclassical approaches break down.
