论文摘要
我们使用超订购的相关器，纠缠轮廓和操作员纠缠来表征两个范式的非热局部阶段和随机单线阶段的运算符和纠缠的增长和纠缠的增长和纠缠。我们将这些阶段与强烈的全息形成形式的田间理论和完全局部的安德森绝缘子进行对比。我们获得了对这些阶段的操作员和状态动力学的现象学描述，并证明了纠缠轮廓和操作员纠缠措施的实用性，作为缓慢争夺和非热动力学的有用探针。
We characterize the growth and spreading of operators and entanglement in two paradigmatic non-thermalizing phases - the many-body localized phase and the random singlet phase - using out-of-time-ordered correlators, the entanglement contour, and operator entanglement. We contrast these phases with strongly thermalizing holographic conformal field theories and fully localized Anderson insulators. We obtain a phenomenological description of the operator and state dynamics of these phases and demonstrate the utility of the entanglement contour and operator entanglement measures as useful probes of slowly scrambling and non-thermalizing dynamics.
