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…
Thermodynamics of Spin-Imbalanced Fermi Gases with SU(N) Symmetric Interaction
Chengdong He, Xin-Yuan Gao, Ka Kwan Pak +6
Thermodynamics of degenerate Fermi gases has been extensively studied through various aspects such as Pauli blocking effects, collective modes, BCS superfluidity, and more. Despite…
Two-dimensional non-Hermitian skin effect in an ultracold Fermi gas
Entong Zhao, Zhiyuan Wang, Chengdong He +6
The concept of non-Hermiticity has expanded the understanding of band topology leading to the emergence of counter-intuitive phenomena. One example is the non-Hermitian skin effect…
Observing a topological phase transition with deep neural networks from experimental images of ultracold atoms
Entong Zhao, Ting Hin Mak, Chengdong He +4
Although classifying topological quantum phases have attracted great interests, the absence of local order parameter generically makes it challenging to detect a topological phase…
