Anomalous wave-packet transport on boundaries of Floquet topological systems
Xin-Xin Yang, Kai-Ye Shi, F. Nur Ünal +1
A two-dimensional periodically driven (Floquet) system with zero winding number in the absence of time-reversal symmetry is usually considered topologically trivial. Here, we study…
Orbital Optical Raman Lattice
Zhi-Hao Huang, Kou-Han Ma, Bao-Zong Wang +2
Spin and orbital are two basic degrees of freedom that play significant roles in exploring exotic quantum phases in optical lattices with synthetic spin-orbit coupling (SOC) and hi…
Preparation and observation of anomalous counterpropagating edge states in a periodically driven optical Raman lattice
Hongting Hou, Long Zhang
Motivated by the recent observation of real-space edge modes with ultracold atoms [Braun et al., Nat. Phys. 20, 1306 (2024)], we investigate the preparation and detection of anomal…
Measuring Non-Hermitian Topological Invariants Directly from Quench Dynamics
Xiao-Dong Lin, Long Zhang
While non-Hermitian (NH) topological phases and phenomena have been observed across various quantum systems, directly measuring NH topological invariants remains a significant chal…
Synthetic Mutual Gauge Field in Microwave-Shielded Polar Molecular Gases
Bei Xu, Fan Yang, Ran Qi +2
The recent breakthrough of realizing the Bose-Einstein condensate of polar molecules and degenerate Fermi molecules in three dimensions relies crucially on the microwave shielding…
Dissipation Driven Coherent Dynamics Observed in Bose-Einstein Condensates
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…
