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

Description:
There exist few configurations of t-electric potential steps and x-electric potential steps (i.e., electric fields that are switched on and off t → ±∞ and x → ±∞, respectively) that admit exact soluti

Description:
Starting from an equation for causal propagator describing Dirac particles interacting with electromagnetic fields and weakly interacting with matter fields, we derive a path integral representation f

Description:
We present a semiclassical approximation for treating the radiation from classical currents. In particular, we present exact quantum states of the quantized electromagnetic field interacting with clas

Description:
We study neutral fermions pair creation with anomalous magnetic moment from the vacuum by time-independent magnetic-field inhomogeneity as an external background.We show that the problem is technicall

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
