Magnetic-Field-Calibration-Free Determination of the Hyperfine Constant in Ultracold Fermi gases of K
Yajing Yang, Biao Shan, Yuhang Zhao +8
Hyperfine constant is a key parameter of the hyperfine structure and underpins precision spectroscopy and metrology. In this Letter, we develop a magnetic-field-calibration-fre…

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…
