Mobility rings in a non-Hermitian non-Abelian quasiperiodic lattice
Rui-Jie Chen, Guo-Qing Zhang, Zhi Li +1
We study localization and topological properties in spin-1/2 non-reciprocal Aubry-André chain with SU(2) non-Abelian artificial gauge fields. The results reveal that, different fro…
Critical properties in the non-Hermitian Aubry-Andre-Stark model
Ji-Long Dong, En-Wen Liang, Shi-Yang Liu +3
We explore the critical properties of the localization transition in the non-Hermitian Aubry-Andre-Stark (AAS) model with quasiperiodic and Stark potentials, where the non-Hermitic…
Localization and topological transitions in non-Hermitian quasiperiodic lattices
Ling-Zhi Tang, Guo-Qing Zhang, Ling-Feng Zhang +1
We investigate the localization and topological transitions in a one-dimensional (interacting) non-Hermitian quasiperiodic lattice, which is described by a generalized Aubry-André-…
Continuous-variable assisted thermal quantum simulation
Dan-Bo Zhang, Guo-Qing Zhang, Zheng-Yuan Xue +2
Simulation of a quantum many-body system at finite temperatures is crucially important but quite challenging. Here we present an experimentally feasible quantum algorithm assisted…
Quantum evolution speed in the finite-temperature bosonic environment
Jun-Qing Cheng, Guo-Qing Zhang, Jing-Bo Xu
We investigate the quantum evolution speed of a qubit in two kinds of finite-temperature environments. The first environment is a bosonic bath with Ohmic-like spectrum. It is found…
