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 cosmological backgrounds
A. A. Saharian, G. V. Mirzoyan, G. H. Harutyunyan +1
We study topological defects with a general structure in higher-dimensional cosmological backgrounds described by a set of angle deficit parameters. As special cases, they include…
Topological Casimir effect in models with helical compact dimensions
R. M. Avagyan, A. A. Saharian, D. H. Simonyan +1
We investigate the influence of the helical compactification of spatial dimension on the local properties of the vacuum state for a charged scalar field with general curvature coup…
Plane symmetric gravitational fields in (D+1)-dimensional General Relativity
R. M. Avagyan, T. A. Petrosyan, A. A. Saharian +1
We consider plane symmetric gravitational fields within the framework of General Relativity in (D+1)-dimensional spacetime. Two classes of vacuum solutions correspond to higher-dim…
Fermionic vacuum stresses in models with toroidal compact dimensions
A. A. Saharian, R. M. Avagyan, G. H. Harutyunyan +1
We investigate vacuum expectation value of the energy-momentum tensor for a massive Dirac field in flat spacetime with a toroidal subspace of a general dimension. Quasiperiodicity…
Qualitative evolution in f(R) cosmologies
R. M. Avagyan, E. V. Chubaryan, G. H. Harutyunyan +1
We investigate the qualitative evolution of (D+1)-dimensional cosmological models in f(R) gravity for the general case of the function f(R). The analysis is specified for various e…
Wightman function and Casimir densities for Robin plates in the Fulling-Rindler vacuum
A. A. Saharian, R. M. Avagyan, R. S. Davtyan
Wightman function, the vacuum expectation values of the field square and the energy-momentum tensor are investigated for a massive scalar field with an arbitrary curvature coupling…
The Casimir effect in the Fulling-Rindler vacuum
R. M. Avagyan, A. A. Saharian, A. H. Yeranyan
The vacuum expectation values of the energy--momentum tensor are investigated for massless scalar fields satisfying Dicichlet or Neumann boundary conditions, and for the electromag…
