Dynamical topological invariant after a quantum quench
Chao Yang, Linhu Li, Shu Chen
We show how to define a dynamical topological invariant for general one-dimensional topological systems after a quantum quench. Focusing on two-band topological insulators, we demo…

Topological invariants for phase transition points of one-dimensional topological systems
Linhu Li, Chao Yang, Shu Chen
We study topological properties of phase transition points of two topologically non-trivial classes (D and DIII) in one dimension by assigning a Berry phase defined…

Winding numbers of phase transition points for one-dimensional topological systems
Linhu Li, Chao Yang, Shu Chen
We study topological properties of phase transition points of one-dimensional topological quantum phase transitions by assigning winding numbers defined on closed circles around th…
