Vacuum instability in time-dependent electric fields. New example of exactly solvable case
A. I. Breev, S. P. Gavrilov, D. M. Gitman +1
A new exactly solvable case in strong-field quantum electrodynamics with a time-dependent external electric field is presented. The corresponding field is given by an analytic func…
Pair production from the vacuum by a weakly inhomogeneous space-dependent electric potential step
S. P. Gavrilov, D. M. Gitman, A. A. Shishmarev
There exists a clear physical motivation for theoretical studies of the vacuum instability related to the production of electron-positron pairs from a vacuum due to strong external…
States of charged quantum fields and their statistical properties in the presence of critical potential steps
S. P. Gavrilov, D. M. Gitman, A. A. Shishmarev
Evolution of charged quantum fields under the action of constant nonuniform electric fields is studied. To this end we construct a special generating functional for density operato…
Particle scattering and vacuum instability by exponential steps
S. P. Gavrilov, D. M. Gitman, A. A. Shishmarev
Particle scattering and vacuum instability in a constant inhomogeneous electric field of particular peak configuration that consists of two (exponentially increasing and exponentia…
Unitarity and vacuum deformation in QED with critical potential steps
S. P. Gavrilov, D. M. Gitman, A. A. Shishmarev
The present article can be considered as a complement to the work P.R.D 93, 045002 (2016) where an nonperturbative approach to QED with x-electric critical potential steps was deve…
Statistical properties of states in QED with unstable vacuum
S. P. Gavrilov, D. M. Gitman, A. A. Shishmarev
We study statistical properties of states of massive quantized charged Dirac and Klein-Gordon fields interacting with a background that violates the vacuum stability, first in gene…
