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…
Vacuum instability in a constant inhomogeneous electric field. A new example of exact nonperturbative calculations
T. C. Adorno, S. P. Gavrilov, D. M. Gitman
Basic quantum processes (such as particle creation, reflection, and transmission on the corresponding Klein steps) caused by inverse-square electric fields are calculated. These re…
Violation of vacuum stability by inverse square electric fields
T. C. Adorno, S. P. Gavrilov, D. M. Gitman
In the framework of QED with a strong background, we study particle creation (the Schwinger effect) by a time-dependent inverse square electric field. To this end corresponding exa…

T. C. Adorno, R. Ferreira, S. P. Gavrilov +1
We find exact differential mean numbers of fermions and bosons created from the vacuum due to a composite electric field of special configuration. This configuration imitates a fin…
Magnetic response from constant backgrounds to Coulomb sources
T. C. Adorno, D. M. Gitman, A. E. Shabad
Magnetically uncharged, magnetic linear response of the vacuum filled with arbitrarily combined constant electric and magnetic fields to an imposed static electric charge is found…
Particle creation by peak electric field
T. C. Adorno, S. P. Gavrilov, D. M. Gitman
The particle creation by the so-called peak electric field is considered. The latter field is a combination of two exponential parts, one exponentially increasing and another expon…

Nonlinear Maxwell equations are written up to the third-power deviations from a constant-field background, valid within any local nonlinear electrodynamics including QED with a Eul…
Exactly solvable cases in QED with t-electric potential steps
T. C. Adorno, S. P. Gavrilov, D. M. Gitman
In this paper, we present in detail consistent QED (and scalar QED) calculations of particle creation effects in external electromagnetic field that correspond to three most import…
When electric charge becomes also magnetic
Tiago C. Adorno, Dmitry M. Gitman, Anatoly E. Shabad
In nonlinear electrodynamics, QED included, we find a static solution to the field equations with an electric charge as its source, which is comprised of homogeneous parallel magne…
Particle creation from the vacuum by an exponentially decreasing electric field
T. C. Adorno, S. P. Gavrilov, D. M. Gitman
We analyze the creation of fermions and bosons from the vacuum by the exponentially decreasing in time electric field in detail. In our calculations we use QED and follow in main t…
Nonlinearity in Electro- and Magneto-statics with and without External Field
T. C. Adorno, Caio Costa, D. M. Gitman +1
Due to the nonlinearity of QED, a static charge becomes a magnetic dipole if placed in a magnetic field. Already without external field, the cubic Maxwell equation for the field of…

It is demonstrated, owing to the nonlinearity of QED, that a static charge placed in a strong magnetic field\ \ is a magnetic dipole (besides remaining an electric monopole, as…
Magnetic response to applied electrostatic field in external magnetic field
T. C. Adorno, D. M. Gitman, A. E. Shabad
We show, within QED and other possible nonlinear theories, that a static charge localized in a finite domain of space becomes a magnetic dipole, if it is placed in an external (con…
Noncommutative magnetic moment, fundamental length and lepton size
T. C. Adorno, D. M. Gitman, A. E. Shabad
Upper bounds on fundamental length are discussed that follow from the fact that a magnetic moment is inherent in a charged particle in noncommutative (NC) electrodynamics. The stro…

In a -noncommutative (NC) gauge field theory we extend the Seiberg-Witten (SW) map to include the (gauge-invariance-violating) external current and formulate - to the…
Noncommutative magnetic moment of charged particles
T. C. Adorno, D. M. Gitman, A. E. Shabad +1
It has been argued, that in noncommutative field theories sizes of physical objects cannot be taken smaller than an elementary length related to noncommutativity parameters. By gau…
