Non-Hermitian bulk-boundary correspondence via scattering theory
Haoshu Li, Qian Niu
The conventional bulk-boundary correspondence breaks down in non-Hermitian systems. In this paper, we reestablish the bulk-boundary correspondence in one-dimensional non-Hermitian…
Dynamic skin effects in non-Hermitian systems
Haoshu Li, Shaolong Wan
We study the time evolution processes of non-Hermitian systems under the open boundary condition and confirm that the dynamical skin effect exists in non-Hermitian systems analytic…
Exact formulas of the end-to-end Green's functions in non-Hermitian systems
Haoshu Li, Shaolong Wan
Green's function in non-Hermitian systems has recently been revealed to be capable of directional amplification in some cases. The exact formulas for end-to-end Green's functions a…
Homotopy invariant in time-reversal and twofold rotation symmetric systems
Haoshu Li, Shaolong Wan
The primary goal of this paper is to study topological invariants in two dimensional twofold rotation and time-reversal symmetric spinful systems. In this paper, firstly we build a…
