Fig. 2. The transfer rate Γν for atoms from the state 3 to the state 2 on a logarithmic scale as a function of the radio-frequency detuning, here, ν denotes the RF detuning in units of the Fermi energy EF/h, the red solid line is the best fit to the data, the inset displays the same data multiplied by 23/2π2ν3/2, while the gray dashed line represents the best-fit red curve multiplied by 23/2π2ν3/2

Fig. 3. 2D momentum distribution of a strongly interacting Fermi gas at temperature T/TF=0.12 on a logarithmic scale, the red solid line represents the best fit to the data, inset is the 2D momentum distribution multiplied by 2/πk3, with the gray dashed line showing the best-fit red curve multiplied by 2/πk3

Fig. 4. Temperature dependence of Contact for a unitary Fermi gas,the blue (red) points represent measurements obtained via the two-photon Raman coupling technique (radio-frequency spectroscopy), while the black solid line denotes the theoretical prediction^[13]
