论文摘要
尽管理论上为了解多体定位（MBL）过渡的微妙而做出了巨大的理论努力，但许多问题仍然是开放的，特别是关于其关键特性。在这里，我们对一个维度的MBL伴随着一种自旋冷冻机制，该机构在热力学极限内导致链断裂。使用分析和数值方法，我们表明这种链破裂直接探测了典型的定位长度，并且它们在MBL过渡时的缩放特性与kosterlitz-现象重新分配组方法预测的kosterlitz-thouless情景一致。
Despite tremendous theoretical efforts to understand subtleties of the many-body localization (MBL) transition, many questions remain open, in particular concerning its critical properties. Here we make the key observation that MBL in one dimension is accompanied by a spin freezing mechanism which causes chain breakings in the thermodynamic limit. Using analytical and numerical approaches, we show that such chain breakings directly probe the typical localization length, and that their scaling properties at the MBL transition agree with the Kosterlitz-Thouless scenario predicted by phenomenological renormalization group approaches.
