Biorthogonal dynamical quantum phase transitions in non-Hermitian topological superconductors
Haoran Gu, Yubo Zhao, Siyuan Cheng +3
Dynamical quantum phase transitions in non-Hermitian systems pose fundamental challenges due to the intrinsic biorthogonality of their eigenstates. In this work, we extend a biorth…

Entanglement signatures of quantum criticality in Floquet non-Hermitian topological systems
Siyuan Cheng, Rui Xie, Xiaosen Yang +2
The entanglement entropy can be an effective diagnostic tool for probing topological phase transitions. In one-dimensional single particle systems, the periodic driving generates a…
