我们研究了具有共振相互作用的a波费米气体的普遍性质，在这种相互作用中，轴对称被自发或外部破坏。在这里，我们证明了短程关联可以完全由九分量波接触张量来表征，而九分量波接触张量可以通过广义绝热扫描定理来测量。波接触张量的独特特征出现在各向异性陷阱中的正常波费米气体中和超流相中。文中还讨论了测量波接触张量和检验绝热扫描定理的实验方案。
We investigate universal properties of a-wave Fermi gas with a resonant interaction in which the axisymmetry is broken spontaneously or externally. Here, we show that the short-range correlations can be completely characterized by the nine-component-wave contact tensor, which can be measured through a generalized adiabatic sweep theorem. The distinctive features of the-wave contact tensor emerge in a normal-wave Fermi gas in an anisotropic trap and in a superfluid phase. An experimental scheme to measure the-wave contact tensor and test the adiabatic sweep theorem is also discussed.
