Super-critical QED-effects via VP-energy
K. Sveshnikov, Yu. Voronina
The properties of the QED-vacuum energy $\hbox{$\cal E $}_{VP}$ under Coulomb super-criticality condition are explored in essentially non-perturbative approach. It is…
Casimir force variability in one-dimensional QED systems
Yu. Voronina, I. Komissarov, K. Sveshnikov
The Casimir force between two short-range charge sources, embedded in a background of one dimensional massive Dirac fermions, is explored by means of the original $\ln\text{[Wronsk…
Essentially non-perturbative and peculiar polarization effects in planar QED with strong coupling
Yu. Voronina, K. Sveshnikov, P. Grashin +1
The essentially non-perturbative polarization effects are considered for a planar supercritical Dirac-Coulomb system with strong coupling (similar to graphene and graphene-based he…
Casimir (vacuum) energy in planar QED with strong coupling
Yu. Voronina, K. Sveshnikov, P. Grashin +1
The essentially non-perturbative vacuum polarization effects, caused by an extended external supercritical Coulomb source, are explored for a planar Dirac-Coulomb (DC) system with…
