Electromagnetic Casimir effect for conducting plates in de Sitter spacetime
A. S. Kotanjyan, A. A. Saharian, H. A. Nersisyan
Two-point functions, the mean field squared and the vacuum expectation value (VEV) of the energy-momentum tensor are investigated for the electromagnetic field in the geometry of p…
Electromagnetic two-point functions and Casimir densities for a conducting plate in de Sitter spacetime
A. A. Saharian, A. S. Kotanjyan, H. A. Nersisyan
We evaluate the two-point function for the electromagnetic field tensor in -dimensional de Sitter spacetime assuming that the field is prepared in Bunch-Davies vacuum state.…
Scalar and fermionic vacuum currents in de Sitter spacetime with compact dimensions
S. Bellucci, A. A. Saharian, H. A. Nersisyan
Vacuum expectation values (VEVs) of the current densities for charged scalar and Dirac spinor fields are investigated in (D+1)-dimensional de Sitter (dS) spacetime with toroidally…
