论文摘要
在干净和肮脏的情况下计算诱导相互作用的效果，以平衡和不平衡的费米气体。我们研究了非磁杂质对在平衡气体的情况下对过渡温度的诱导相互作用校正以及在单位性不平衡费米气体不平衡的情况下对过渡温度的影响。我们发现，对于过渡温度和三个临界点而言，杂质会损害诱导的相互作用或粒子孔波动。对于大杂质参数，粒子孔波动被强烈抑制。我们还发现，考虑到纯度和杂质的诱导相互作用的效果，在纯种和杂质方面的效果考虑到纯平的费米气体的chandrasekhar-clogston极限。
The effects of induced interactions are calculated in both clean and dirty situations, for balanced and imbalanced Fermi gases. We investigate the effects of nonmagnetic impurities on the induced interactions corrections to the transition temperature in the case of a balanced gas, and to the tricritical point in the case of an imbalanced Fermi gas at unitarity. We find that impurities act in detriment of the induced interactions, or particle-hole fluctuations, for the transition temperature and the tricritical point. For large impurity parameter, the particle-hole fluctuations are strongly suppressed. We have also found the Chandrasekhar-Clogston limit of an imbalanced Fermi gas at unitarity considering the effects of the induced interactions, both in the pure and impurity regimes.
