Quench dynamics of Hopf insulators
Haiping Hu, Chao Yang, Erhai Zhao
Hopf insulators are exotic topological states of matter outside the standard ten-fold way classification based on discrete symmetries. Its topology is captured by an integer invari…

Signature of nonequilibrium quantum phase transition in the long time average of Loschmidt echo
Bozhen Zhou, Chao Yang, Shu Chen
We unveil the role of the long time average of Loschmidt echo in the characterization of nonequilibrium quantum phase transitions by studying sudden quench processes across quantum…

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…
