Improving Euler-Heisenberg-Schwinger effective action with dressed photons
Stefan Evans, Johann Rafelski
We implement a longstanding proposal by Weisskopf to apply virtual polarization corrections to the in/out external fields in study of the Euler-Heisenberg-Schwinger effective actio…
Study of QED singular properties for variable gyromagnetic ratio
Johann Rafelski, Stefan Evans, Lance Labun
Using the external field method, {\it i.e.\/} evaluating the effective action for an arbitrarily strong constant and homogeneous field, we explore nonperturbativ…
Singular properties of QED vacuum response to applied quasi-constant electromagnetic fields
Stefan Evans, Johann Rafelski
Employing the Bogoliubov coefficient summation method and introducing the gyromagnetic ratio we derive an explicit functional form of , the…
Emergence of periodic in magnetic moment effective QED action
Stefan Evans, Johann Rafelski
We evaluate for the inhomogeneous static electric Sauter step potential the imaginary part of the emerging homogeneous in electric field effective Euler-Heisenberg-Schwinger action…
Particle production at a finite potential step: Transition from Euler-Heisenberg to Klein paradox
Stefan Evans, Johann Rafelski
Spontaneous pair production for spin- and spin- particles is explored in a quantitative manner for a static -Sauter potential step (SS), evaluating the imaginary par…
Electron EM-mass melting in strong fields
Stefan Evans, Johann Rafelski
We study the response of the electron mass to an externally applied electrical field. As a consequence of nonlinear electromagnetic (EM) effective action, the mass of a particle di…
