Topological invariants, zero mode edge states and finite size effect for a generalized non-reciprocal Su-Schrieffer-Heeger model
Hui Jiang, Rong Lü, Shu Chen
Intriguing issues in one-dimensional non-reciprocal topological systems include the breakdown of usual bulk-edge correspondence and the occurrence of half-integer topological invar…

Interplay of non-Hermitian skin effects and Anderson localization in non-reciprocal quasiperiodic lattices
Hui Jiang, Li-Jun Lang, Chao Yang +2
Non-Hermiticity from non-reciprocal hoppings has been shown recently to demonstrate the non-Hermitian skin effect (NHSE) under open boundary conditions (OBCs). Here we study the in…

Topological classification of non-Hermitian systems with reflection symmetry
Chun-Hui Liu, Hui Jiang, Shu Chen
We classify topological phases of non-Hermitian systems in the Altland-Zirnbauer classes with an additional reflection symmetry in all dimensions. By mapping the non-Hermitian syst…
