Edge State, Band Topology, and Time Boundary Effect in the Fine-Grained Categorization of Chern Insulators
H. C. Wu, H. S. Xu, L. C. Xie +1
We predict novel topological phases with broken time-reversal symmetry supporting the coexistence of opposite chiral edge states, which are fundamentally different from the photoni…
Topology of anti-parity-time-symmetric non-Hermitian Su-Schrieffer-Heeger model
H. C. Wu, L. Jin, Z. Song
We propose an anti-parity-time (anti-PT ) symmetric non-Hermitian Su-Schrieffer-Heeger (SSH) model, where the large non-Hermiticity constructively creates nontrivial topology and g…
Inversion symmetric non-Hermitian Chern insulator
H. C. Wu, L. Jin, Z. Song
We propose a two-dimensional non-Hermitian Chern insulator with inversion symmetry, which is anisotropic and has staggered gain and loss in both x and y directions. In this system,…
Topological Phase Transition Independent of System Non-Hermiticity
K. L. Zhang, H. C. Wu, L. Jin +1
Non-Hermiticity can vary the topology of system, induce topological phase transition, and even invalidate the conventional bulk-boundary correspondence. Here, we show the introduci…
