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…
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…
