Add   Spectra of electronic excitations in graphene near coulomb impurities
Authors: Breev, A. I. | Ferreira, Robson | Gitman, Dmitri M. | Voronov, B. L.
Source: Journal of experimental and theoretical physics. 2020. Vol. 130, № 5. P. 711-736
Type: статьи в журналах
Date: 2020
Description: We study the problem of the electron excitation spectrum in the presence of point-like and regularized Coulomb impurities in gapped graphene. To this end, we use the Dirac model and in the point-like ... More
Add   Vacuum quantum effects on Lie groups with bi-invariant metrics
Authors: Breev, A. I. | Shapovalov, Alexander V.
Source: International journal of geometric methods in modern physics. 2019. Vol. 16, № 8. P. 1950122 (1-28)
Type: статьи в журналах
Date: 2019
Description: We consider the effects of vacuum polarization and particle creation of a scalar field on Lie groups with a non-stationary bi-invariant metric of the Robertson–Walker type. The vacuum expectation valu ... More
Add   Interaction between two point-like charges in nonlinear electrostatics
Authors: Breev, A. I. | Shabad, Anatoly E.
Source: The European physical journal C. 2018. Vol. 78, № 1. P. 39 (1-10)
Type: статьи в журналах
Date: 2018
Description: We consider two point-like charges in electrostatic interaction within the framework of a nonlinear model, associated with QED, that provides finiteness of their field energy. We find the common field ... More
Add   Symmetry operators and separation of variables in the (2 + 1)-dimensional Dirac equation with external electromagnetic field
