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...
In view of the inadequacy interactivity and ecological aesthetics in park landscape, existing methods are often difficult to achieve accurate terrain analysis design, resulting unsatisfactory landscape effects. order make up for this shortcoming, research innovatively integrates sparrow search algorithm (SSA) self-organizing mapping (SOM) conduct in-depth topography. SSA, with its powerful global ability, can quickly lock optimal solution region. SOM uses unsupervised learning effectively...
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....
