在过去已经提出了几种方法来研究费米子的半经典动力学。讨论的主要议题是纳入泡利原则，即：具有平行自旋的两个电子必须处于正交态。在过去，这有时是通过增加排斥泡利势或通过使用反对称试探态来实现的。在这篇文章中，我们表明：（a）使用基于经典轨迹的半经典传播子足以解释泡利原理，但（B）半经典波函数方法是不能令人满意的。
Several approaches to the semiclassical dynamics of fermions have been proposed in the past. The main subject under discussion was the inclusion of the Pauli principle, i.e., the fact that two electrons with parallel spins must be in orthogonal states. In the past, this was sometimes achieved by adding repulsive Pauli potentials or by using antisymmetric trial states. In this article we show that (a) the use of semiclassical propagators based on classical trajectories is sufficient to account for the Pauli principle, but (b) a semiclassical wave-function approach is not satisfactory.
