我们考虑自旋弛豫动力学在冷费米气体与纯规范自旋轨道耦合对应于最近的实验。我们表明，这样的实验可以提供一个直接访问的碰撞自旋阻力率，并建立条件的观察自旋阻力效应。在最近的实验中发现，动力学主要是弹道导致新的制度的可逆自旋弛豫过程。
We consider spin relaxation dynamics in cold Fermi gases with a pure-gauge spin-orbit coupling corresponding to recent experiments. We show that such experiments can give a direct access to the collisional spin drag rate, and establish conditions for the observation of spin drag effects. In the recent experiments the dynamics is found to be mainly ballistic leading to new regimes of reversible spin relaxation-like processes.
