Relativistic corrections to the algebra of position variables and spin-orbital interaction
arXiv:1609.00043 · doi:10.1016/j.physletb.2016.08.034
Abstract
In the framework of vector model of spin, we discuss the problem of a covariant formalism \cite{Pomeranskii1998} concerning the discrepancy between relativistic and Pauli Hamiltonians. We show how the spin-induced non commutativity of a position accounts the discrepancy on the classical level, without appeal to the Dirac equation and Foldy-Wouthuysen transformation.
