Canonical quantization of Dirac spinning particle in the external electromagnetic field

摘要

The canonical quantization of Dirac spinning particle in the external electromagnetic field in the space-time dimension D=4 is carried out in a gauge which allows to describe antiparticles already at the classical level. The Newton-Wigner type coordinates and momentum for a particle in the external electromagnetic field are found. 11 refs. (Atomindex citation 27:071393)
