Spectra of electronic excitations in graphene near Coulomb impurities
A. I. Breev, R. Ferreira, D. M. Gitman +1
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 an…
In- and out-states of scalar particles confined between two capacitor plates
A. I. Breev, S. P. Gavrilov, D. M. Gitman
In the present article, using a non-commutative integration method of linear differential equations, we, considering the Klein-Gordon equation with the -constant electric field…
Vacuum quantum effects on Lie groups with bi-invariant metrics
A. I. Breev, A. V. Shapovalov
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 vac…
Spinor field singular functions in QED with strong external backgrounds
A. I. Breev, S. P. Gavrilov, D. M. Gitman
We construct and study singular functions in strong-field with two external electromagnetic fields that represent principally different types of external backgrounds, the fir…
