Rotation and Spin and Position Operators in Relativistic Gravity and Quantum Electrodynamics
First, we examine how spin is treated in special relativity and the necessity of introducing spin supplementary conditions (SSC) and how they are related to the choice of a center-of-mass of a spinning particle. Next, we discuss quantum electrodynamics and the Foldy−Wouthuysen transformati...
