High-Quality Axion Models with the Anomalous Gauge Symmetry
Hongkun Gao, Tianjun Li, Lina Wu +1
We propose the generic high-quality axion models with anomalous gauge symmetry and vector-like particles. We briefly review the gauge anomaly cancellations via the Green-S…
Observation of non-Hermitian bulk-boundary correspondence in non-chiral non-unitary quantum dynamics of single photons
Miao Zhang, Yue Zhang, Shuai Li +9
The breakdown of conventional bulk-boundary correspondence, a cornerstone of topological physics, is one of counter-intuitive phenomena in non-Hermitian systems, that is deeply roo…
Non-chiral non-Bloch invariants and topological phase diagram in non-unitary quantum dynamics without chiral symmetry
Yue Zhang, Shuai Li, Yingchao Xu +7
The non-Bloch topology leads to the emergence of various counter-intuitive phenomena in non-Hermitian systems under the open boundary condition (OBC), which can not find a counterp…
Localization-delocalization Transition in an electromagnetically induced photonic lattice
Rui Tian, Shuai Li, Maksims Arzamasovs +3
We investigate the localization-delocalization transition (LDT) in an electromagnetically induced photonic lattice. A four-level tripod-type scheme in atomic ensembles is proposed…
