Topological effects in the polarization of the Fulling-Rindler vacuum
A. A. Saharian, G. V. Mirzoyan, V. S. Torosyan
We investigate how the compactification of some spatial dimensions in Rindler spacetime affects the vacuum expectation values (VEVs) of the field squared and the energy-momentum te…
Electromagnetic Wightman functions and vacuum densities for a brane intersecting the AdS boundary
A. A. Saharian, R. M. Avagyan, V. F. Manukyan
We investigate the combined effects of a brane intersecting the AdS boundary and background gravitational field on the local characteristics of the electromagnetic vacuum. Two type…
Topological defects and scalar field modes in warped geometries
A. A. Saharian, E. L. Karapetyan, G. V. Mirzoyan
We develop a general framework for investigating the influence of topological defects on the local characteristics of a quantum scalar field in a warped geometry background. The Ri…
Radiation processes in dielectric cylindrical waveguides
A. A. Saharian, L. Sh. Grigoryan, H. F. Khachatryan
Dielectric cylindrical waveguides are widely used for confining and guiding of electromagnetic waves in relatively wide range of frequencies. They have found numerous technological…
Fermionic Casimir densities for a uniformly accelerating mirror in the Fulling-Rindler vacuum
A. A. Saharian, L. Sh. Grigoryan, V. Kh. Kotanjyan
We investigate the local characteristics of the Fulling-Rindler vacuum for a massive Dirac field induced by a planar boundary moving with constant proper acceleration in -di…
Two-point functions and the vacuum densities in the Casimir effect for the Proca field
A. A. Saharian, H. H. Asatryan
We investigate the properties of the vacuum state for the Proca field in the geometry of two parallel plates on background of (D+1)-dimensional Minkowski spacetime. The two-point f…
