论文摘要
我们在数字上探索$ \ Mathbb Z_2 $ - 对称的随机交互作用Ising-Majorana链，高能。出现了非常丰富的相图，具有两个拓扑不同的多体定位（MBL）态度，其热相距比以前发现的更广泛的热相。这是雪崩理论的显着结果。我们进一步发现MBL旋转玻璃顺序始终与多体频谱配对相关联，大概是向强零模式运算符发出的，这为MBL保护受到的拓扑量表打开了迷人的视角。
We numerically explore $\mathbb Z_2$-symmetric random interacting Ising-Majorana chains at high energy. A very rich phase diagram emerges with two topologically distinct many-body localization (MBL) regimes separated by a much broader thermal phase than previously found. This is a striking consequence of the avalanche theory. We further find MBL spin-glass order always associated to a many-body spectral pairing, presumably signaling a strong zero mode operator which opens fascinating perspectives for MBL-protected topological qubits.
