论文摘要
多体局部（MBL）相中的强烈无序系统可以在高度激发的本征态中表现出基态秩序。定位，对称性和拓扑之间的相互作用导致了MBL相的广阔景观的表征，从自旋玻璃和时间晶体到对称性受保护的拓扑相。了解这些不同形式的本征状秩序之间的相位过渡的性质仍然是一个必不可少的开放问题。在这里，我们猜测可能不会发生不同的MBL顺序之间的直接过渡。相反，热相总是干预。在基于Rydberg-ATOM的量子模拟的最新进展中，我们提出了一种实验方案，可以通过局部可观察到的动力学来诊断中间的热相。
Strongly disordered systems in the many-body localized (MBL) phase can exhibit ground state order in highly excited eigenstates. The interplay between localization, symmetry, and topology has led to the characterization of a broad landscape of MBL phases ranging from spin glasses and time crystals to symmetry protected topological phases. Understanding the nature of phase transitions between these different forms of eigenstate order remains an essential open question. Here, we conjecture that no direct transition between distinct MBL orders can occur; rather, a thermal phase always intervenes. Motivated by recent advances in Rydberg-atom-based quantum simulation, we propose an experimental protocol where the intervening thermal phase can be diagnosed via the dynamics of local observables.
