Finite temperature current densities and Bose-Einstein condensation in topologically nontrivial spaces
E. R. Bezerra de Mello, A. A. Saharian
We investigate the finite temperature expectation values of the charge and current densities for a complex scalar field with nonzero chemical potential in background of a flat spac…
Fermionic vacuum polarization by a flat boundary in cosmic string spacetime
E. R. Bezerra de Mello, A. A. Saharian, S. V. Abajyan
In this paper we investigate the fermionic condensate and the renormalized vacuum expectation value (VEV) of the energy-momentum tensor for a massive fermionic field induced by a f…
Fermionic current from topology and boundaries with applications to higher-dimensional models and nanophysics
S. Bellucci, A. A. Saharian
We investigate combined effects of topology and boundaries on the vacuum expectation value (VEV) of the fermionic current in the space with an arbitrary number of toroidally compac…
Casimir-Polder interaction between an atom and a conducting wall in cosmic string spacetime
E. R. Bezerra de Mello, V. B. Bezerra, H. F. Mota +1
The Casimir-Polder interaction potential is evaluated for a polarizable microparticle and a conducting wall in the geometry of a cosmic string perpendicular to the wall. The genera…
Quantum effects in higher-dimensional cosmological models
A. A. Saharian
Vacuum energy density and stresses are investigated for a scalar field in de Sitter spacetime with an arbitrary number of toroidally compactified spatial dimensions and in anti-de…
Scalar self-energy for a charged particle in global monopole spacetime with a spherical boundary
E. R. Bezerra de Mello, A. A. Saharian
We analyze combined effects of the geometry produced by global monopole and a concentric spherical boundary on the self-energy of a point-like scalar charged test particle at rest.…
