在单色非绝热调制的横场驱动下，建立了伊辛模型的一组非平衡量子相变。我们发现，除了伊辛样的临界行为，该系统表现出各向异性的过渡，这是不存在的平衡。非平衡量子相位对应于长时间动力学中与外部控制同步的状态。DOI：10.1103/PhysRevA.86.063627
We establish a set of nonequilibrium quantum phase transitions in the Ising model driven under monochromatic nonadiabatic modulation of the transverse field. We show that besides the Ising-like critical behavior, the system exhibits an anisotropic transition which is absent in equilibrium. The nonequilibrium quantum phases correspond to states which are synchronized with the external control in the long-time dynamics. DOI:10.1103/PhysRevA.86.063627
