论文摘要
两个组分的费米气体的旋转以及随后的涡流出现已成为众多实验和理论研究的主题。在超细状态依赖性电位和高度退化异核费米气体的最新实验进步表明，在未来的实验中创建依赖组分的旋转电位是可行的。在这项研究中，我们使用有效的现场理论来考虑费米气体仅旋转费米气体的一个成分的效果。我们发现，散装中的超流体带隙存在至较高的旋转频率，因为静止的超氟距离涡流的静止频率仅一半仅能抵抗旋转效应的一半。涡流仍然是高于临界频率的能量有利状态，但表现出较大的核心大小。
The rotation of two-component Fermi gases and the subsequent appearance of vortices have been the subject of numerous experimental and theoretical studies. Recent experimental advances in hyperfine state-dependent potentials and highly degenerate heteronuclear Fermi gases suggest that it would be feasible to create component-dependent rotation potentials in future experiments. In this study we use an effective field theory for Fermi gases to consider the effects of rotating only one component of the Fermi gas. We find that the superfluid band gap in bulk exists up to higher rotation frequencies because the superfluid at rest, far away from the vortex, has to resist only half of the rotational effects. The vortex remains the energetically favorable state above a critical frequency but exhibits a larger core size.
