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...
Absorption imaging is the foundation for quantitative measurements in experiments on ultracold atoms. This technique mainly involves capturing images of both probing light field and atom absorption field. In this process, unavoidable jitter introduces noise fringe patterns into atomic optical density distribution OD. conventional removal algorithms, type can be normalized by constructing an optimal reference image from multiple that have been actually taken, which shares similar to (Fig....
