Dirac particle in Newman-Unti-Tamburino spacetime
N. G. Krylova, V. M. Red'kov
We derive the Dirac equation for a particle in the background of the Newman-Unti-Tamburino (NUT) spacetime by applying the tetrad formalism, and separate the angular and radial par…

Expansions of the solutions of the general Heun equation in terms of the incomplete Beta functions
T. A. Shahverdyan, V. M. Red'kov, A. M. Ishkhanyan
Applying the approach based on the equation for the derivative, we construct several expansions of the solutions of the general Heun equation in terms of the incomplete Beta functi…

Adiabatic asymmetric scattering of atoms in the field of a standing wave
M. V. Hakobyan, V. M. Red'kov, A. M. Ishkhanyan
A model of the asymmetric coherent scattering process (caused by initial atomic wave-packet splitting in the momentum space) taking place at the large detuning and adiabatic course…
