Vacuum polarization by a cosmic string in de Sitter spacetime
In this paper we investigate the vacuum polarization effect associated with a quantum massive scalar field in a higher dimensional de Sitter spacetime in the presence of a cosmic string. Because this investigation has been developed in a pure de Sitter space, here we are mainly interested on the effects induced by the presence of the string. So this analysis is developed by expressing the compl...
متن کاملInduced fermionic currents in de Sitter spacetime in the presence of a compactified cosmic string
We investigate the vacuum fermionic currents in the geometry of a compactified cosmic string on background of de Sitter spacetime. The currents are induced by magnetic fluxes running along the cosmic string and enclosed by the compact dimension. We show that the vacuum charge and the radial component of the current density vanish. By using the Abel-Plana summation formula, the azimuthal and axi...
متن کاملThe Energy-momentum Tensor in Fulling-rindler Vacuum
The energy density in Fulling-Rindler vacuum, which is known to be negative " everywhere " is shown to be positive and singular on the horizons in such a fashion as to guarantee the positivity of the total energy. The mechanism of compensation is displayed in detail. 1 1. Introduction In connection with the problem of the radiation emitted and absorbed by an accelerating observer [1, 2, 3, 10, ...
متن کاملVacuum Polarization Effects in Higher Dimensional Global Monopole Spacetime
In this paper we analyse the vacuum polarization effects associated with a massless scalar field in higher-dimensional global monopole spacetime. Specifically we calculate the renormalized vacuum expectation value of the field square, 〈Φ(x)〉Ren, induced by a global monopole. Two different spacetimes will be considered: i) In the first, the global monopole lives in whole universe, and ii) in the...
متن کاملFermionic vacuum densities in higher - dimensional de Sitter spacetime
Fermionic condensate and the vacuum expectation values of the energy-momentum tensor are investigated for twisted and untwisted massive spinor fields in higher-dimensional de Sitter spacetime with toroidally compactified spatial dimensions. The expectation values are presented in the form of the sum of corresponding quantities in the uncompactified de Sitter spacetime and the parts induced by n...
