Second sound attenuation, a distinctive dissipative hydrodynamic phenomenon in superfluid, is crucial for understanding superfluidity and elucidating critical phenomena. Here, we report the observation of second attenuation homogeneous Fermi gas lithium-6 atoms at unitarity by performing Bragg spectroscopy with high energy resolution long-wavelength limit. We successfully obtained temperature dependence diffusivity [Formula: see text] thermal conductivity κ. Furthermore, observed sudden...
The nature of pseudogap lies at the heart strongly-interacting superconductivity and superfluidity. With known pairing interactions, unitary Fermi gases provide an ideal testbed to verify whether a can arise from many-body pairing. Here we report observation long-sought pair-fluctuation-driven in homogeneous lithium-6 atoms, by precisely measuring spectral function through momentum-resolved microwave spectroscopy without serious effects final-state effect. We find large above superfluid...
