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…

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…

Vacuum currents in elliptic pseudosphere tubes
A. A. Saharian, G. V. Mirzoyan
We examine the effects of spatial topology, curvature, and magnetic flux on the vacuum expectation value (VEV) of the current density for a charged scalar field in (2+1)-dimensiona…
