Radiation of breathing vortex electron packets in magnetic field
G. V. Zmaga, G. K. Sizykh, D. V. Grosman +4
When a vortex electron with an orbital angular momentum (OAM) enters a magnetic field, its quantum state is described with a nonstationary Laguerre-Gaussian (NSLG) state rather tha…
Photon emission by vortex particles accelerated in a linac
A. Yu. Murtazin, G. K. Sizykh, D. V. Grosman +3
We study the photon emission by charged spinless particles with phase vortices and an orbital angular momentum (OAM) projection in longitudinal electric and magnetic fields within…
Phase-space description of photon emission
D. V. Karlovets, A. A. Shchepkin, A. D. Chaikovskaia +4
Interactions between charged particles and light occur in real space and time, yet quantum field theory usually describes them in momentum space. Whereas this approach is well suit…
Generating entangled pairs of vortex photons via induced emission
D. V. Grosman, G. K. Sizykh, E. O. Lazarev +2
Pairs of entangled vortex photons can promise new prospects of application in quantum computing and cryptography. We investigate the possibility of generating such states via two-l…
Nonstationary Laguerre-Gaussian states in magnetic field
G. K. Sizykh, A. D. Chaikovskaia, D. V. Grosman +2
The Landau states of electrons with orbital angular momentum in magnetic fields are important in the quantum theories of metals and of synchrotron radiation at storage rings, in re…
Absorption of a twisted photon by an electron in strong magnetic field
A. A. Shchepkin, D. V. Grosman, I. I. Shkarupa +1
The work investigates absorption of a twisted photon, which possesses quantized total angular momentum (TAM), by a relativistic electron with the Lorentz factor in a…
