囚禁费米气体中正常-超流边界的弹性理论

Elastic theory of Normal-Superfluid Boundary in trapped Fermi Gases

Stefan S. Natu, Erich J. Mueller

摘要:

将极化费米气体中的正常-超流边界模拟为弹性膜,计算了原子密度分布。对于小的捕获各向异性,我们发现,超流正常边界保持近似椭圆形,并具有不同于陷阱的纵横比。对于非常长的云,边界被扭曲成类似于胶囊的形状。我们提出了一个分析解释这种形状。

英文摘要:

By modeling the normal-superfluid boundary in a trapped polarized Fermi gas as an elastic membrane, we calculate the atomic density profile. For small trapping anisotropy, we find that the superfluid-normal boundary remains approximately elliptical, and has an aspect ratio different from that of the trap. For very prolate clouds the boundary becomes distorted into a capsule-like shape. We present an analytic explanation of this shape.
