Non-Hermitian bulk-boundary correspondence and auxiliary generalized Brillouin zone theory
Zhesen Yang, Kai Zhang, Chen Fang +1
We provide a systematic and self-consistent method to calculate the generalized Brillouin Zone (GBZ) analytically in one dimensional non-Hermitian systems, which helps us to unders…
Fermion doubling theorems in 2D non-Hermitian systems for Fermi points and exceptional points
Zhesen Yang, A. P. Schnyder, Jiangping Hu +1
The fermion doubling theorem plays a pivotal role in Hermitian topological materials. It states, for example, that Weyl points must come in pairs in three-dimensional semimetals. H…
Jones polynomial and knot transitions in topological semimetals
Zhesen Yang, Ching-Kai Chiu, Chen Fang +1
Topological nodal line semimetals host stable chained, linked, or knotted line degeneracies in momentum space protected by symmetries. In this paper, we use the Jones polynomial as…
Quasi 1D topological nodal vortex line phase in doped superconducting 3D Dirac Semimetals
Shengshan Qin, Lunhui Hu, Congcong Le +4
We study the vortex bound states in three dimensional (3D) superconducting Dirac semimetals with time reversal symmetry. Assuming two Dirac points on the kz-axis and bulk s-wave su…
