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…

Dynamical signature of localization-delocalization transition in one-dimensional incommensurate lattice
Chao Yang, Yucheng Wang, Pei Wang +2
We investigate the quench dynamics of a one-dimensional incommensurate lattice described by the Aubry-André model by a sudden change of the strength of incommensurate potential …
