Acoustic corner states in topological insulators with built-in Zeeman-like fields
Xueqin Huang, Jiuyang Lu, Zhongbo Yan +4
The higher-order topological insulators (HOTIs), with such as the topological corner states, emerge as a thriving topic in the field of topological physics. But few connections hav…
Synthetic Hall tube of interacting fermions
Xiaofan Zhou, Gang Chen, Suotang Jia
Motivated by a recent experiment [J. H. Han, et. al., Phys. Rev. Lett.122, 065303 (2019)], we investigate many-body physics of interacting fermions in a synthetic Hall tube, using…
A new method for driven-dissipative problems: Keldysh-Heisenberg equations
Yuanwei Zhang, Gang Chen
Driven-dissipative systems have recently attracted great attention due to the existence of novel physical phenomena with no analog in the equilibrium case. The Keldysh path-integra…
Dynamical Zeeman resonance in spin-orbit-coupled spin-1 Bose gases
Jingtao Fan, Gang Chen, Suotang Jia
We predict a dynamical resonant effect, which is driven by externally applied linear and quadratic Zeeman fields, in a spin-orbit-coupled spin-1 Bose-Einstein condensate. The Bose-…
Higher-order topological semimetal in acoustic crystals
Qiang Wei, Xuewei Zhang, Weiyin Deng +6
The notion of higher-order topological insulators has endowed materials with topological states beyond the first order. Particularly, a three-dimensional (3D) higher-order topologi…
Atomic self-organization emerging from tunable quadrature coupling
Jingtao Fan, Gang Chen, Suotang Jia
The recent experimental observation of dissipation-induced structural instability provides new opportunities for exploring the competition mechanism between stationary and nonstati…
