Axiomatic quantum electrodynamics: from causality to convexity of effective action
Anatoly E. Shabad
Theory of electromagnetic field, specified by an effective action functional, is considered. The causality condition is imposed in the form of a requirement that the group velociti…
Singular electromagnetic fields in nonlinear electrodynamics with a constant background field
T. C. Adorno, D. M. Gitman, A. E. Shanad
When exploring equations of nonlinear electrodynamics in effective medium formed by mutually parallel external electric and magnetic fields, we come to special static axial-symmetr…
Axion Electrodynamics in Strong Magnetic Backgrounds
Selym Villalba-Chávez, Anatoly E. Shabad, Carsten Müller
The overcritical regime of axion-electrodynamics (AED) is investigated. For magnetic fields larger than the characteristic scale linked to AED, quantum vacuum fluctuations due to a…
Comment on Cherenkov radiation in magnetized vacuum
A. E. Shabad
The Cherenkov radiation in the vacuum with constant magnetic background is denied within quantum kinematics in spite of the refractive index of that equivalent medium being greater…
Saturation of Energy Levels of the Hydrogen Atom in Strong Magnetic Field
T. C. Adorno, D. M. Gitman, A. E. Shabad
We demonstrate that the finiteness of the limiting values of the lower energy levels of a hydrogen atom under an unrestricted growth of the magnetic field, into which this atom is…
Selection rules for light-by-light scattering in strong magnetic field
A. E. Shabad
Selection rules that follow from CP- and 4-momentum conservation are listed for head-on light-by-light scattering in strong magnetic field taking into account nontrivial dispersion…
