Floquet topological phases of non-Hermitian systems
H Wu, JH An - Physical Review B, 2020 - APS
The non-Hermiticity caused breakdown of the bulk-boundary correspondence (BBC) in
topological phase transition was cured by the skin effect for the systems with chiral symmetry …

Topological characterizations of an extended Su–Schrieffer–Heeger model
Abstract The Su–Schrieffer–Heeger (SSH) model perhaps is the easiest and the most basic
model for topological excitations. Many variations and extensions of the SSH model have …

Non-Hermitian Floquet topological phases in the double-kicked rotor
L Zhou, J Pan - Physical Review A, 2019 - APS
Dynamical kicking systems possess rich topological structures. In this work we study Floquet
states of matter in a non-Hermitian extension of the double-kicked rotor model. Under the on …
