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…
