我们提出了一个统一的概述，从平均场到统一状态，具有短程吸引相互作用的捕获费米气体的稳定性。与玻色子系统不同，费米气体在这些体系中总是稳定的，无论粒子数有多大。然而，当粒子间距与原子间相互作用的范围相当时，不稳定性就不被排除了。
We present a unified overview, from the mean-field to the unitarity regime, of the stability of a trapped Fermi gas with short range attractive interactions. Unlike in a system of bosons, a Fermi gas is always stable in these regimes, no matter how large the particle number. However, when the interparticle spacing becomes comparable to the range of the interatomic interactions, instability is not precluded.
