Boundary-Controlled Liouvillian Relaxation with Exact Steady States Fixed by Dissipative Disorder
Yazhuang Miao, Weizh Ma, Yong Wang +2
In open quantum lattice systems, changing the boundary condition would appear to alter both the steady state and the nonzero Liouvillian spectrum. Here we show that boundary condit…
Imaginary Gauge-steerable Edge Modes In Non-Hermitian Aubry-André-Harper Model
Yazhuang Miao, Wei Ding, Litong Wang +3
We identify steerable exponentially localized in-gap mode in a quasiperiodic non-Hermitian Aubry-André-Harper chain with a spatially fluctuating, zero-mean imaginary gauge field. U…
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…
A Strategy for Preparing Quantum Squeezed States Using Reinforcement Learning
X. L. Zhao, Y. M. Zhao, M. Li +4
We propose a scheme leveraging reinforcement learning to engineer control fields for generating non-classical states. It is exemplified by the application to prepare spin-squeezed…
