Abstract

We consider the semiclassical theory in a joint phase space of spin and orbital degrees of freedom. The method is developed from the path integral using the spin-coherent-state representation, and yields the trace formula for the density of states. We discuss the limits of weak and strong spin–orbit coupling and relate the present theory to the earlier approaches.
