Expanding quantum Proca field
Bogdan Damski
We consider the Proca theory of a real massive vector field coupled to an external current. This theory allows for non-conservation of the charge associated with the external curre…
Non-equilibrium dynamics of long-range field configurations in the Proca theory and the counterexample to the law of periodic charge oscillations
Bogdan Damski
Long-range field configurations exist in the Proca theory and their non-equilibrium evolution is of interest in this work. General arguments suggest that a charge can be assigned t…
Reference frame dependence of the periodically oscillating Coulomb field in the Proca theory
Bogdan Damski
The Proca theory of the real massive vector field admits non-equilibrium solutions, where the asymptotic dynamics of its electric field is dominated by the periodically oscillating…
Electromagnetic angular momentum of the electron: One-loop studies
Bogdan Damski
We study angular momentum of the electron stored in its electric and magnetic fields. We use for this purpose quantum electrodynamics in the covariant gauge. We show that a finite…
