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 MUBs and Maximizers of Magick
Bogdan S. Damski, RafaÅ BistroÅ, Diego Ponterio +2
In this work we investigate discrete structures in product Hilbert spaces. For monopartite systems of size one relies on the Weyl-Heisenberg group , while in the case of…
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…
