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…
