本文介绍并研究了在光子泄漏和相干源驱动下，由非线性元件耦合的QED腔阵列的性质。非线性耦合导致光子跳跃和最近邻克尔项。通过调整系统参数，阵列的稳态可以呈现与光子阻断的周期性调制相关联的光子晶体。在某些情况下，晶体有序化可以与相位同步共存。我们考虑的这类腔阵列可以用现有技术的超导电路来建造。DOI：10.1103/PhysRevLett.110.163605
We introduce and study the properties of an array of QED cavities coupled by nonlinear elements, in the presence of photon leakage and driven by a coherent source. The nonlinear couplings lead to photon hopping and to nearest-neighbor Kerr terms. By tuning the system parameters, the steady state of the array can exhibit a photon crystal associated with a periodic modulation of the photon blockade. In some cases, the crystalline ordering may coexist with phase synchronization. The class of cavity arrays we consider can be built with superconducting circuits of existing technology.
