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…
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…
Universal competitive spectral scaling from the critical non-Hermitian skin effect
Fang Qin, Ye Ma, Ruizhe Shen +1
Recently, it was discovered that certain non-Hermitian systems can exhibit qualitative different properties at different system sizes, such as being gapless at small sizes and havi…
Light-induced phase crossovers in a quantum spin Hall system
Fang Qin, Ching Hua Lee, Rui Chen
In this work, we theoretically investigate the light-induced topological phases and finite-size crossovers in a paradigmatic quantum spin Hall (QSH) system with high-frequency pump…
Non-Hermitian Squeezed Polarons
Fang Qin, Ruizhe Shen, Ching Hua Lee
Recent experimental breakthroughs in non-Hermitian ultracold atomic lattices have dangled tantalizing prospects in realizing exotic, hitherto unreported, many-body non-Hermitian qu…
