Experimental study of matter-wave four-wave mixing in K Bose-Einstein condensates with tunable interaction
Yue Zhang, Liangchao Chen, Zekui Wang +7
We experimentally investigate four-wave mixing (FWM) of matter waves in two geometric configurations in K Bose-Einstein condensates with the atomic interaction tuned via Fes…
Experimental study of magnetically insensitive transitions in ultracold Fermi gas of K
Biao Shan, Lianghui Huang, Yajing Yang +8
This paper presents an experimental study of microwave single-photon transitions that are magnetic-field-insensitive in degenerate Fermi gases of K. This contrasts with micr…
Tetratomic states of microwave dressed and associated ultracold 23Na40K molecules
Zhengyu Gu, Xuansheng Zhou, Wei Chen +5
Ultracold diatomic molecules have achieved significant breakthroughs in recent years, enabling the exploration of quantum chemistry, precision measurements, and strongly correlated…
Observation of quantized vortex in an atomic Bose-Einstein condensate at Dirac point with emergent spin-orbit coupling
Yunda Li, Wei Han, Zengming Meng +3
When two or more energy bands become degenerate at a singular point in the momentum space, such singularity, or ``Dirac points", gives rise to intriguing quantum phenomena as well…
Topologically nontrivial and trivial flat bands via weak and strong interlayer coupling in twisted bilayer honeycomb optical lattices for ultracold atoms
Wenjie Sui, Wei Han, Zheng Vitto Han +2
In recent years, flat electronic bands in twisted bilayer graphene (TBG) have attracted significant attention due to their intriguing topological properties, extremely slow electro…
Chiral Raman coupling for spin-orbit coupling in ultracold atomic gases
Biao Shan, Lianghui Huang, Yuhang Zhao +4
Spin-orbit coupling (SOC) in ultracold atoms is engineered by light-atom interaction, such as two-photon Raman transitions between two Zeeman spin states. In this work, we propose…
