Defective Edge States and Anomalous Bulk-Boundary Correspondence in non-Hermitian Topological Systems
Xiao-Ran Wang, Cui-Xian Guo, Su-Peng Kou
Non-Hermitian topological systems show quite different properties as their Hermitian counterparts. An important, puzzled issue on non-Hermitian topological systems is the existence…
Parity Anomaly of Lattice Maxwell Fermions in Two Spatial Dimensions
Jiang Zhou, Xiaosi Qi, Yajie Wu +1
Unconventional lattice fermions with high degeneracies beyond Weyl and Dirac fermions have attracted intensive attention in recent years. In this paper, attention is drawn to the p…
Non-Hermitian Dynamic Strings and Anomalous Topological Degeneracy on non-Hermitian Toric-code Model with Parity-time Symmetry
Cui-Xian Guo, Xiao-Ran Wang, Su-Peng Kou
In this paper, with the help of Hermitian/non-Hermitian dynamic strings, the theory of non-Hermitian topological order is developed based on a non-Hermitian Wen-plaquette model. Th…
Fidelity as a probe for a deconfined quantum critical point
Gaoyong Sun, Bo-Bo Wei, Su-Peng Kou
Deconfined quantum critical point was proposed as a second-order quantum phase transition between two broken symmetry phases beyond the Landau-Ginzburg-Wilson paradigm. However, nu…
