The dynamical and topological properties of non-Hermitian systems have attracted great attention in recent years. In this work, we establish an intrinsic connection between two classes of intriguing phenomena—topological phases and dynamical quantum phase transitions (DQPTs)—in non-Hermitian systems. Focusing on one-dimensional models with chiral symmetry, we find DQPTs following the quench from a trivial to a non-Hermitian topological phase. Moreover, the critical momenta and critical time of… Expand

TLDR
This work systematically explore Floquet DQPTs in a class of periodically quenched one-dimensional system with chiral symmetry by tuning the strength of quench, which opens a new perspective for the Floquet engineering of D QPTs and the dynamical detection of topological phase transitions in Floquet systems.
