Geometric phase of Wannier-Stark ladders in alkaline-earth(-like) atoms
De-Huan Cai, Wei Yi
We discuss the geometric phase of Wanner-Stark ladders generated by periodically driven clock states in alkaline-earth(-like) atoms. Using Yb atoms as a concrete example, w…
Dissipation-facilitated molecules in a Fermi gas with non-Hermitian spin-orbit coupling
Lihong Zhou, Wei Yi, Xiaoling Cui
We study the impact of non-Hermiticity on the molecule formation in a two-component spin-orbit-coupled Fermi gas near a wide Feshbach resonance. Under an experimentally feasible co…
Observation of non-Hermitian bulk-boundary correspondence in quantum dynamics
Lei Xiao, Tianshu Deng, Kunkun Wang +4
Bulk-boundary correspondence, a central principle in topological matter relating bulk topological invariants to edge states, breaks down in a generic class of non-Hermitian systems…
Topology with broken parity-time symmetry
Lei Xiao, Xingze Qiu, Kunkun Wang +3
Topological edge states arise in parity-time ()-symmetric non-unitary quantum dynamics but have so far only been discussed in the -symmetry-unbroken reg…
Topological quantum walks in momentum space with a Bose-Einstein condensate
Dizhou Xie, Tian-Shu Deng, Teng Xiao +4
We report the experimental implementation of discrete-time topological quantum walks of a Bose-Einstein condensate in momentum space. Introducing stroboscopic driving sequences to…
Two-body bound state of ultracold Fermi atoms with two-dimensional spin-orbit coupling
Shu Yang, Fan Wu, Wei Yi +1
In a recent experiment, a two-dimensional spin-orbit coupling (SOC) was realized for fermions in the continuum [Nat. Phys. 12, 540 (2016)], which represents an important step forwa…
