Fermionic vacuum polarization by a composite topological defect in higher-dimensional space-time
E. R. Bezerra de Mello, A. A. Saharian
We investigate the vacuum polarization effects associated with a charged massless spin-1/2 field in a higher-dimensional space-time, induced by a composite topological defect. The…
Fermionic Casimir effect in toroidally compactified de Sitter spacetime
A. A. Saharian
We investigate the fermionic condensate and the vacuum expectation values of the energy-momentum tensor for a massive spinor field in de Sitter spacetime with spatial topology $\ma…
Wightman function and vacuum densities in de Sitter spacetime with toroidally compactified dimensions
S. Bellucci, A. A. Saharian
We investigate the Wightman function, the vacuum expectation values of the field square and the energy-momentum tensor for a scalar field with general curvature coupling parameter…
On features of the radiation from an electron moving along a helix inside a cylindrical hole in a homogeneous dielectric
S. R. Arzumanyan, L. Sh. Grigoryan, H. F. Khachatryan +2
The radiation from a charge moving along a helical trajectory inside a cylindrical hole in homogeneous dielectric medium is investigated. Prompted by availability of materials with…
Vacuum densities for a thick brane in AdS spacetime
A. A. Saharian, A. L. Mkhitaryan
For a massive scalar field with general curvature coupling parameter we evaluate Wightman function, vacuum expectation values of the field square and the energy-momentum tensor ind…
Casimir effect in de Sitter spacetime with compactified dimension
A. A. Saharian, M. R. Setare
We investigate the Hadamard function, the vacuum expectation values of the field square and the energy-momentum tensor of a scalar field with general curvature coupling parameter i…
