标题： Strong and Weak Many-Body Localizations

摘要： 许多多体局域（MBL）的方面，包括MBL相的动力学分类，仍然难以理解。 在这里，通过执行实空间重正化群（RSRG）分析，我们提出存在两种不同类型的MBL相：“强MBL”由准周期（QP）势引起， 以及“弱MBL”由随机势引起。 强MBL和弱MBL相可以通过它们不同的热包含概率分布和纠缠熵来区分：在强MBL相中呈指数衰减，而在弱MBL相中呈幂律衰减。 我们进一步讨论了存在两种不同类型的MBL相的潜在机制以及实验意义。 由QP势引起的强MBL可能为量子信息存储和处理提供一个更鲁棒且有前景的平台。 显示英文摘要

摘要： Many aspects of many-body localization (MBL), including dynamic classification of MBL phases, remain elusive. Here, by performing real-space renormalization group (RSRG) analysis we propose that there are two distinct types of MBL phases: "strong MBL" induced by quasiperiodic (QP) potential and "weak MBL" induced by random potential. Strong and weak MBL phases can be distinguished by their different probability distributions of thermal inclusion and entanglement entropy: exponential decay in strong MBL phases but power-law decay in weak MBL. We further discuss underlying mechanisms as well as experimental implications of having two distinct types of MBL phases. Strong MBL induced by QP potential may provide a more robust and promising platform for quantum information storage and processing.
