Interaction of twisted light with free twisted atoms
I. Pavlov, A. Chaikovskaia, D. Karlovets
We investigate absorption and scattering of structured light by atoms, treating the photon and the atomic center of mass as spatially localized wave packets. We show that vortex ph…
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…
Angular momentum effects in neutron decay
I. Pavlov, A. Chaikovskaia, D. Karlovets
We investigate the intriguing phenomenon of beta decay of a free neutron in a non-plane-wave(structured) state. Our analysis covers three types of states: unpolarized vortex (Besse…
Attosecond physics hidden in Cherenkov radiation
D. Karlovets, A. Chaikovskaia, D. Grosman +3
Cherenkov radiation of charged particles moving with superluminal velocities in transparent media is a well-studied phenomenon with a plethora of applications. Its microscopic orig…
Generation of vortex electrons by atomic photoionization
I. I. Pavlov, A. D. Chaikovskaia, D. V. Karlovets
We explore the process of orbital angular momentum (OAM) transfer from a twisted light beam to an electron in atomic ionization within the first Born approximation. The characteris…
Elastic scattering of Laguerre-Gaussian electron packets on atoms
N. Sheremet, A. Chaikovskaia, D. Grosman +1
We explore elastic scattering of non-relativistic electrons in the form of standard Laguerre-Gaussian (sLG) and elegant Laguerre - Gaussian (eLG) packets on atomic targets in the g…
Vavilov-Cherenkov emission with a twist: a study of the final entangled state
A. D. Chaikovskaia, D. V. Karlovets, V. G. Serbo
We present a theoretical investigation of the Vavilov-Cherenkov (VC) radiation by a plane-wave or twisted electron. Special emphasis is put on the question whether and at what cond…
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…
Transmission of vortex electrons through a solenoid
G. K. Sizykh, A. D. Chaikovskaia, D. V. Grosman +2
We argue that it is generally nonstationary Laguerre-Gaussian states (NSLG) rather than the Landau ones that appropriately describe electrons with orbital angular momentum both in…
Studying highly relativistic vortex-electron beams by atomic scattering
V. K. Ivanov, A. D. Chaikovskaia, D. V. Karlovets
We explore the opportunities of using electron scattering by screened Coulomb potential as a tool to retrieve properties of the relativistic vortex beams of electrons, such as thei…
