Add   Massless electronic excitations in graphene near Coulomb impurities
Authors: Breev, Alexander I. | Gitman, Dmitri M.
Source: Journal of experimental and theoretical physics. 2021. Vol. 132, № 6. P. 941-959
Type: статьи в журналах
Date: 2021
Description: We study low-energy massless electronic excitations in a graphene monolayer near a pointlike Coulomb impurity. We assume that such excitations are described by the Dirac model. We construct a family o ... More
Add   Vacuum instability in time-dependent electric fields: New example of an exactly solvable case
Authors: Breev, Alexander I. | Gavrilov, Sergey P. | Gitman, Dmitri M. | Shishmarev, A. A.
Source: Physical Review D. 2021. Vol. 104, № 7. P. 076008-1-076008-14
Type: статьи в журналах
Date: 2021
Description: A new exactly solvable case in strong-field quantum electrodynamics with a time-dependent external electric field is presented. The corresponding field is given by one component of the electromagnetic ... More
