Non-Abelian Gauge Enhances Self-Healing for Non-Hermitian Su--Schrieffer--Heeger Chain
Yazhuang Miao, Yiming Zhao, Yong Wang +3
We investigate a non-Hermitian extension of the Su--Schrieffer--Heeger model that incorporates spin-dependent SU(2) gauge fields, represented by non-Abelian couplings between latti…

Non-Abelian Gauge Effect for 2-D Non-Hermitian Hatano-Nelson Model in Cylinder Type
Yiming Zhao, Yazhuang Miao, Yihang Xing +3
Non-Abelian gauge offers a powerful route to engineer novel topological phenomena. Here, we systematically investigate a two-dimensional (2D) non-Hermitian Hatano-Nelson model inco…

Reinforcement Learning Enhancing Entanglement for Two-Photon-Driven Rabi Model
Tingting Li, Yiming Zhao, Yong Wang +3
A control scheme is proposed that leverages reinforcement learning to enhance entanglement by modulating the two-photon-driven amplitude in a Rabi model. The quantum phase diagram…
