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…
