Electron-acoustic phonon field induced tunnel scattering
S. V. Melkonyan, A. L. Harutyunyan, T. A. Zalinyan
Theory of electron-acoustic single phonon scattering has been reconsidered. It is assumed that the non-degenerate semiconductor has a spherical parabolic band structure. In the bas…
Electromagnetic Casimir effect for conducting plates in de Sitter spacetime
A. S. Kotanjyan, A. A. Saharian, H. A. Nersisyan
Two-point functions, the mean field squared and the vacuum expectation value (VEV) of the energy-momentum tensor are investigated for the electromagnetic field in the geometry of p…
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…
Automorphism groups of endomorphism semigroups of free periodic groups
Varujan S. Atabekyan
In this paper we describe the automorphism groups of the endomorphism semigroups of free Burnside groups for odd exponents . We prove, that the groups $Aut(End(B…
The Hopfian Property of -Periodic Products of Groups
S. I. Adian, V. S. Atabekyan
Let be a subgroup of a group . A normal subgroup of is said to be inheritably normal if there is a normal subgroup of such that . It is pr…
On the detection of point sources in Planck LFI 70 GHz CMB maps based on cleaned K-map
H. G. Khachatryan, A. L. Kashin, E. Poghosian +1
We use the Planck LFI 70GHz data to further probe point source detection technique in the sky maps of the cosmic microwave background (CMB) radiation. The method developed by Tegma…
