Topological invariants and phase diagrams for one-dimensional two-band non-Hermitian systems without chiral symmetry
Hui Jiang, Chao Yang, Shu Chen
We study topological properties of one-dimensional non-Hermitian systems without chiral symmetry and give phase diagrams characterized by topological invariants and $ν_{total…

Observation of dynamical quantum phase transition by a superconducting qubit simulation
Xue-Yi Guo, Chao Yang, Yu Zeng +7
A dynamical quantum phase transition can occur during time evolution of sudden quenched quantum systems across a phase transition. It corresponds to the nonanalytic behavior at a c…
