Hybrid exceptional point created from type III Dirac point
L. Jin, H. C. Wu, Bo-Bo Wei +1
Degeneracy (exceptional) points embedded in energy band are distinct by their topological features. We report different hybrid two-state coalescences (EP2s) formed through merging…
Helical resonant transport and purified amplification at an exceptional point
K. L. Zhang, L. Jin, Z. Song
We propose an application of a parity-time symmetric non-Hermitian Su-Schrieffer-Heeger (SSH) model by embedded it in a two-dimensional square lattice tube. The coalescence state a…
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…
