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…
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…
Activating non-Hermitian skin modes by parity-time symmetry breaking
Zhoutao Lei, Ching Hua Lee, Linhu Li
Parity-time () symmetry is a cornerstone of non-Hermitian physics as it ensures real energies for stable experimental realization of non-Hermitian phenomena. In this…
Proposal for Observing Yang-Lee Criticality in Rydberg Atomic Arrays
Ruizhe Shen, Tianqi Chen, Mohammad Mujahid Aliyu +4
Yang-Lee edge singularities (YLES) are the edges of the partition function zeros of an interacting spin model in the space of complex control parameters. They play an important rol…
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…
