Interaction of twisted light with free twisted atoms
I. Pavlov, A. Chaikovskaia, D. Karlovets
The paper studies how structured, vortex-shaped light beams interact with atoms when both are treated as localized wave packets, showing that orbital angular momentum can be transf…
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…
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…
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…
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…
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…
