Light-induced half-quantized Hall effect and axion insulator
Fang Qin, Ching Hua Lee, Rui Chen
Motivated by the recent experimental realization of the half-quantized Hall effect phase in a three-dimensional (3D) semi-magnetic topological insulator [M. Mogi et al., Nature Phy…

Kinked linear response from non-Hermitian cold-atom pumping
Fang Qin, Ruizhe Shen, Linhu Li +1
It is well known that non-Hermitian, non-reciprocal systems may harbor exponentially localized skin modes. However, in this work, we find that, generically, non-Hermiticity gives r…

Topological Non-Hermitian skin effect
Rijia Lin, Tommy Tai, Mengjie Yang +2
This article reviews recent developments in the non-Hermitian skin effect (NHSE), particularly on its rich interplay with topology. The review starts off with a pedagogical introdu…
