Vacuum photon emission and mean electromagnetic field in pair-creating external backgrounds
I. A. Aleksandrov, E. V. Perelygin, D. V. Chubukov
We develop a perturbative description of vacuum radiative processes in quantum electrodynamics with a prescribed external electromagnetic background capable of producing electron-p…
Vacuum polarization and pair production in time-dependent electric fields: A quantum-kinetic-equation approach
I. A. Aleksandrov, V. A. Bokhan, A. I. Baksheev +1
The evolution of the vacuum state in a time-dependent external electric field of arbitrary polarization is investigated within a nonperturbative framework of quantum kinetic equati…
Evolution of a twisted electron wave packet perturbed by an inhomogeneous electric field
A. Kudlis, I. A. Aleksandrov, N. N. Rosanov
Laguerre-Gaussian (LG) wave packets, known for their vortex structure and nonzero orbital angular momentum (OAM), are of great interest in various scientific fields. Here we study…
Semiclassical kinetic equations for composite bosons
A. Kudlis, I. A. Aleksandrov, Y. S. Krivosenko +1
We derive semiclassical Boltzmann equations describing thermalization of an ensemble of excitons due to exciton-phonon interactions taking into account the fact that excitons are n…
Pair production in rotating electric fields via quantum kinetic equations: Resolving helicity states
I. A. Aleksandrov, A. Kudlis
We investigate the phenomenon of electron-positron pair production from vacuum in the presence of a strong electric field of circular polarization. By means of a nonperturbative ap…
Kinetic theory of vacuum pair production in uniform electric fields revisited
I. A. Aleksandrov, A. Kudlis, A. I. Klochai
We investigate the phenomenon of electron-positron pair production from vacuum in the presence of a uniform time-dependent electric field of arbitrary polarization. Taking into acc…
Theory of biexciton-polaritons in transition metal dichalcogenide monolayers
Andrey Kudlis, Ivan A. Aleksandrov, Mikhail M. Glazov +1
We theoretically investigate a nonlinear optical response of a planar microcavity with an embedded transition metal dicalcogenide monolayer when the energy of a biexcitonic transit…
A trion in a magnetic field revisited
I. A. Aleksandrov, A. Kudlis, I. A. Shelykh
We revisit the problem of a two dimensional trion in an external magnetic field. We demonstrate that the approximations used previously for finding the energy spectrum of this syst…
Stimulated vacuum emission and photon absorption in strong electromagnetic fields
I. A. Aleksandrov, A. Di Piazza, G. Plunien +1
According to quantum electrodynamics (QED), a strong external field can make the vacuum state decay producing electron-positron pairs. Here we investigate emission of soft photons…
Total yield of electron-positron pairs produced from vacuum in strong electromagnetic fields: validity of the locally constant field approximation
D. G. Sevostyanov, I. A. Aleksandrov, G. Plunien +1
The widely-used locally constant field approximation (LCFA) can be utilized in order to derive a simple closed-form expression for the total number of particles produced in the pre…
Electron-positron pair production in external electric fields varying both in space and time
I. A. Aleksandrov, G. Plunien, V. M. Shabaev
The Schwinger mechanism of electron-positron pair production in the presence of strong external electric fields is analyzed numerically for the case of one- and two-dimensional fie…
