Source: Journal of synchrotron radiation. 2020. Vol. 27, P. 4. P. 902-911
Type: статьи в журналах
Date: 2020
Description: Synchrotron radiation was originally studied by classical methods using the Liénard–Wiechert potentials of electric currents. Subsequently, quantum corrections to the classical formulas were studied, ... More
Source: Physical Review D. 2019. Vol. 99, № 11. P. 116014-1-116014-14
Type: статьи в журналах
Date: 2019
Description: 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 electric fields. Va ... More
Source: Physical Review A. 2019. Vol. 99, № 5. P. 052116-1-052116-23
Type: статьи в журналах
Date: 2019
Description: 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 operators of the quantum fi ... More
Source: International journal of modern physics A. 2018. Vol. 33, № 21. P. 1850128-1-1850128-31
Type: статьи в журналах
Date: 2018
Description: In this paper, we consider two examples of an entanglement in two-qubit systems and an example of entanglement in quantum field theory (QFT). In the beginning, we study the entanglement of two spin st ... More
Source: Physical Review D. 2017. Vol. 96, № 9. P. 096020-1-096020-17
Type: статьи в журналах
Date: 2017
Description: Particle scattering and vacuum instability in a constant inhomogeneous electric field of particular peak configuration that consists of two (exponentially increasing and exponentially decreasing) inde ... More
Source: Physica scripta. 2017. Vol. 92, № 5. P. 054005 (1-6)
Type: статьи в журналах
Date: 2017
Description: In a simple nonlinear model stemming from quantum electrodynamics wherein the pointlike charge has finite field-self-energy, we demonstrate that the latter can be presented as a soliton with its energ ... More
Source: Russian physics journal. 2017. Vol. 59, № 11. P. 1775-1787
Type: статьи в журналах
Date: 2017
Description: Due to the nonlinearity of QED, a static charge becomes a magnetic dipole if placed in a magnetic field, and a magnetic monopole on the background is a combination of constant electric and magnetic fi ... More
Source: Physical Review A. 2015. Vol. 91, № 5. P. 052106-1-052106-13
Type: статьи в журналах
Date: 2015
Description: 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 general terms and then f ... More
