Simple approach to relativistic spin dynamics

Spin dynamics is considered from the point of view of relativistic classical mechanics. It is shown that the assumptions of the Bargmann-Michel-Telegdi theory may be used to obtain an intuitive and convenient equation of motion. The advantage of this approach is that the presence of Thomas precessio...

Description
Summary:Spin dynamics is considered from the point of view of relativistic classical mechanics. It is shown that the assumptions of the Bargmann-Michel-Telegdi theory may be used to obtain an intuitive and convenient equation of motion. The advantage of this approach is that the presence of Thomas precession is automatically and manifestly demonstrated. An easy and unambiguous way to achieve the original Bargmann-Michel-Telegdi equation is also proposed.
