Coupled Orbital and Spin Dynamics of Particles with Magnetic Moments

We propose a consistent unified framework for describing the coupled dynamics of orbital motion and magnetic moments for generic charge carriers. Our general approach naturally covers phenomena such as spin precession and magnetization transport, including the spin Hall effect and its inverse, but it also applies to apparently unrelated phenomena such as the Aharonov-Casher effect and the Stern-Gerlach effect. We will present selected examples to illustrate the power of our approach.
