Dynamic transition of the density-matrix topology under parity-time symmetry
Wenzhi Wang, Wei Yi
Density-matrix topology, defined through the geometric property of the relevant modular Hamiltonian, can undergo transitions in the corresponding open-system dynamics. While symmet…

Biorthogonal topological charge pumping in non-Hermitian systems
Zhenming Zhang, Tianyu Li, Xiwang Luo +1
We study charge pumping in generic non-Hermitian settings and show that quantized charge pumping is only guaranteed under a biorthogonal formalism therein, where the charge transpo…
