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   Role of switching-on and -off effects in the vacuum instability
Authors: Ferreira, Robson | Gavrilov, Sergey P. | Gitman, Dmitri M. | Adorno, Tiago C.
Source: International journal of modern physics A. 2018. Vol. 33, № 11. P. 1850060-1-1850060-18
Type: статьи в журналах
Date: 2018
Description: 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 finite switching-on and ... More
Add   Peculiarities of pair creation by a peak electric field
Authors: Adorno, Tiago C. | Gitman, Dmitri M. | Ferreira, Robson | Gavrilov, Sergey P.
Source: Russian physics journal. 2017. Vol. 60, № 3. P. 417-426
Type: статьи в журналах
Date: 2017
Description: Exact, numerical, and asymptotic calculations concerning the vacuum instability by the so-called peak electric field are explored in detail. Peculiarities discussed in this article are complementary t ... More
