论文摘要
远程交互系统中多体定位的命运尚未完全解决。例如，千古和多体局部制度之间的相边界仍在争论中。在这里，我们使用Floquet动力学，可以通过时空疾病在干净的长距离相互作用系统中诱导多体定位，这是通过随机局部旋转的常规操作来实现的。已经确定了两种类型的均匀和非均匀的远程耦合的相图。我们的浮雕机制比常规静态障碍方法显示出更大的本地化功率，因为它推动了相位边界，而有利于局部阶段。此外，我们的全面长期模拟为基于静态分析获得的结果提供了强有力的支持。
The fate of many-body localization in long-range interacting systems is not fully settled. For instance, the phase boundary between ergodic and many-body localized regimes is still under debate. Here, we use Floquet dynamics which can induce many-body localization in a clean long-range interacting system through spatiotemporal disorder, which are realized by regular operation of random local rotations. The phase diagram has been determined for two types of uniform and nonuniform long-range couplings. Our Floquet mechanism shows more localizing power than conventional static disorder methods as it pushes the phase boundary in favor of the localized phase. Moreover, our comprehensive long-time simulations provide strong support for obtained results based on static analysis.
