Polarization of the conformal vacuum in the Milne universe

T. A. Petrosyan

The vacuum expectation values (VEVs) of the field squared and energy-momentum tensor for a massless scalar field are investigated in the Milne universe with general number of spati…

Casimir densities induced by a sphere in the hyperbolic vacuum of de Sitter spacetime

A. A. Saharian, T. A. Petrosyan

Complete set of modes and the Hadamard function are constructed for a scalar field inside and outside a sphere in (D+1)-dimensional de Sitter spacetime foliated by negative constan…

Casimir effect for fermion condensate in conical rings

A. A. Saharian, T. A. Petrosyan, A. A. Hovhannisyan

The fermion condensate (FC) is investigated for a (2+1)-dimensional massive fermionic field confined on a truncated cone with an arbitrary planar angle deficit and threaded by a ma…

Angular distribution of high power radiation from a charge rotating around a dielectric ball

L. Sh. Grigoryan, A. A. Saharian, H. F. Khachatryan +3

We study the angular distribution of the radiation from a relativistic charged particle uniformly rotating along an equatorial orbit around a dielectric ball. Earlier it was shown…
