Fermionic condensate is investigated in (D+1)-dimensional de Sitter spacetime by using the cutoff function regularization. In order to fix the renormalization ambiguity for massive fields an additional condition is imposed, requiring the condensate to vanish in the infinite mass limit. For large values of the field mass the condensate decays exponentially in odd dimensional spacetimes and follows a power law decay in even dimensional spacetimes. For a massless field the fermionic condensate…

Fermionic 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
The fermionic Casimir effect in toroidally compactified de Sitter spacetime
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 Rp × (S1)q. Both cases
Scalar field instability in de Sitter space time
Starting from the equation of motion of the quantum operator of a real scalar field φ in de Sitter space–time, a simple differential equation is derived which describes the evolution of quantum
One-loop f(R) gravity in de Sitter universe
Motivated by the dark energy issue, the one-loop quantization approach for a family of relativistic cosmological theories is discussed in some detail. Specifically, general f(R) gravity at the
A new vacuum state in de Sitter space
Abstract We present a new vacuum state which can be defined in a region of de Sitter space. This region corresponds to a K =−1 Robertson-Walker coordinatization of de Sitter space. The renormalized
Thermal expectation values of fermions on anti-de Sitter space-time
Making use of the symmetries of anti-de Sitter space-time, we derive an analytic expression for the bispinor of parallel transport, from which we construct in closed form the vacuum Feynman Green's
Particle Physics and Inflationary Cosmology
With the invention of unified theories of strong, weak, electromagnetic and gravitational interactions, elementaryparticle physics has entered a very interesting and unusual stage of its development.

THE memoir in which Bessel, the astronomer, examined in detail the functions which now bear his name was published in 1824, and was the outcome of his earlier researches concerning the expression of
