Quantum Avalanche Stability of Many-Body Localization with Power-Law Interactions
Longhui Shen, Bin Guo, Zhaoyu Sun
We investigate the stability of the many-body localized phase against quantum avalanche instabilities in a one-dimensional Heisenberg spin chain with long-range power-law interacti…

Unified Bulk-Entanglement Correspondence in Non-Hermitian Systems
Xudong Zhang, Zhaoyu Sun, Bin Guo
The non-Hermitian skin effect (NHSE) fundamentally invalidates the conventional bulk-boundary correspondence (BBC), leading topological diagnostics into a crisis. While the non-Blo…
