对于种群不平衡的共振相互作用费米气体，计算了由于少数自旋种的存在而引起的多数自旋种之间的诱导相互作用。结果表明，这种相互作用导致最近观测到的极化子费米液相在低温下不稳定到p波超流体状态。我们发现相关的转变温度，虽然在弱相互作用的BCS体系中相当小，但在强相互作用的幺正体系中是可以得到的。
The induced interaction among the majority spin species, due to the presence of the minority species, is computed for the case of a population-imbalanced resonantly interacting Fermi gas. It is shown that this interaction leads to an instability, at low temperatures, of the recently observed polaron Fermi liquid phase of strongly imbalanced Fermi gases to a p-wave superfluid state. We find that the associated transition temperature, while quite small in the weakly interacting BCS regime, is experimentally accessible in the strongly interacting unitary regime.
