Optimizing the Sensitivity-Noise Trade-off in Non-Hermitian Sensing via Off-Exceptional-Deficiency Operation
Shangxuan Li, Bin Guo
A central challenge in non-Hermitian sensing is that spectral singularities simultaneously amplify both the signal and environmental noise. We address this predicament in a double-…
Intrinsic Mirror Symmetry and Robustness of Optimal Nonlocal Operators in One-Dimensional Quantum Spin Chains
Jia Bao, Bin Guo, Shu Qu +3
Multipartite nonlocality has been extensively investigated within one-dimensional quantum lattices. Previous research has primarily focused on the nonlocality measure , which qu…
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…
