Exceptionally Slow Relaxation from Micro-canonical to Canonical Ensembles in Quasi-one-dimensional Quantum Gases
Huaichuan Wang, Xixiang Du, Zhongchi Zhang +8
Integrability in one dimension prevents quantum thermalization and gives rise to rich many-body phenomena described by generalized hydrodynamics, which have been extensively studie…

Ye Tian, Yajuan Zhao, Yue Wu +10
We report the first experimental observation of dissipation-driven coherent quantum many-body oscillation, and this oscillation is manifested as the coherent exchange of atoms betw…

Chang Liu, Zhe-Yu Shi, Ce Wang
We study the many-body dynamics of weakly interacting Bose gases with two-particle losses. We show that both the two-body interactions and losses in atomic gases may be tuned by co…

We consider the problem of a fixed impurity coupled to a small number of non-interacting bosons. We focus on impurity-boson interactions that are mediated by a closed-channel m…
