Hunan University Finds Quasi-NHEB Scaling Differs From Standard NHEB

Researchers at the School of Physics and Electronics, Hunan University, have discovered a new effect in non-Hermitian quantum systems: a quasi-non-Hermitian edge burst that can occur even without the non-Hermitian skin effect. The team, including Ze Yang and Wei Li, demonstrated that spatially nonuniform loss, or the distribution of energy dissipation within a material, is key to generating this burst of loss probability at system boundaries. Their analysis reveals the “quasi-NHEB” follows a bulk, edge scaling relation distinct from conventional NHEB, suggesting a different underlying mechanism. The results show that boundary-localized loss anomalies can arise from loss distribution alone, providing new insight…
