Electromagnetic vacuum densities induced by a cosmic string
A. A. Saharian, V. F. Manukyan, N. A. Saharyan
We investigate the influence of a generalized cosmic string in (D+1) -dimensional spacetime on the local characteristics of the electromagnetic vacuum. Two special cases are consid…
Electromagnetic vacuum fluctuations around a cosmic string in de Sitter spacetime
A. A. Saharian, V. F. Manukyan, N. A. Saharyan
The electromagnetic field correlators are evaluated around a cosmic string in background of -dimensional dS spacetime assuming that the field is prepared in the Bunch-Davies…
Electromagnetic Casimir densities for a cylindrical shell on de Sitter space
A. A. Saharian, V. F. Manukyan, N. A. Saharyan
Complete set of cylindrical modes is constructed for the electromagnetic field inside and outside a cylindrical shell in the background of % -dimensional dS spacetime. On th…
Casimir effect for scalar current densities in topologically nontrivial spaces
S. Bellucci, A. A. Saharian, N. A. Saharyan
We evaluate the Hadamard function and the vacuum expectation value (VEV) of the current density for a charged scalar field, induced by flat boundaries in spacetimes with an arbitra…
Wightman function and the Casimir effect for a Robin sphere in a constant curvature space
S. Bellucci, A. A. Saharian, N. A. Saharyan
We evaluate the Wightman function, the mean field squared and the vacuum expectation value (VEV) of the energy-momentum tensor for a scalar field with Robin boundary condition on a…
