长程多体系统中的Floquet诱导局域化

Floquet-induced localization in long-range many-body systems

摘要:

长程相互作用系统中多体局域化的命运尚未完全确定。例如,遍历和多体局域化制度之间的相边界仍在争论中。在这里,我们使用Floquet动力学,它可以诱导多体局域化在一个干净的远程相互作用系统通过时空无序,这是实现随机本地旋转的规则操作。确定了均匀和非均匀两种长程耦合的相图。我们的Floquet机制比传统的静态无序方法显示出更大的局域化能力,因为它推动了有利于局域相的相边界。此外,我们全面的长时间模拟提供了强有力的支持所获得的结果的基础上静态分析。

英文摘要:

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.
