Localization behavior in a Hermitian and non-Hermitian Raman lattice

Entong Zhao, Yu-Jun Liu, Ka Kwan Pak +4

We propose a flexible Raman lattice system for alkaline-earth-like atoms to theoretically investigate localization behaviors in a quasi-periodic lattice with controllable non-Hermi…

Third-Order Exceptional Point in Non-Hermitian Spin-Orbit-Coupled cold atoms

Yu-Jun Liu, Ka Kwan Pak, Peng Ren +4

Exceptional points (EPs) has seen substantial advances in both experiment and theory. However, in quantum systems, higher-order exceptional points remain of great interest and poss…

Complete Interband Transitions for Non-Hermitian Spin-Orbit-Coupled Cold-Atom Systems

Dong Liu, Zejian Ren, Wai Chun Wong +5

Recently, synthetic spin-orbit coupling has been introduced into cold-atom systems for more flexible control of the Hamiltonian, which was further made time-varying through two-pho…
