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…
Expanding quantum magnetic field
Bogdan Damski
We develop the quantum theory of the causal formation of a long-range magnetic field generated by an external current that is instantaneously switched on and subsequently kept cons…
Product Weyl--Heisenberg covariant mutually unbiased bases and extremal non-stabilizerness
Bogdan S. Damski, Rafał Bistroń, Diego Ponterio +2
Discrete structures in product Hilbert spaces are investigated. For monopartite systems of size one relies on the Weyl--Heisenberg group , while in the case of composite…
Lorentz transformations in 1+1 dimensional spacetime: mainly the superluminal case
Bogdan S. Damski
We discuss the most general form of the Lorentz transformation in 1+1 dimensional spacetime, focusing mainly on its superluminal branch. For this purpose, we introduce the 2-veloci…
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…
