Stochastic Quantization of Scalar Fields in de Sitter Spacetime
We consider the stochastic quantization method for scalar fields defined in a curved manifold. The two-point function associated to a massive self-interacting scalar field is evaluated, up to the first order level in the coupling constant λ, for the case of de Sitter Euclidean metric. Its value for the asymptotic limit of the Markov parameter τ → ∞ is exhibited. We discuss in detail the covaria...
متن کاملStochastic Quantization of Scalar Fields in Einstein and Rindler Spacetime
We consider the stochastic quantization method for scalar fields defined in a curved manifold and also in a flat space-time with event horizon. The two-point function associated to a massive self-interacting scalar field is evaluated, up to the first order level in the coupling constant λ, for the case of an Einstein and also a Rindler Euclidean metric, respectively. Its value for the asymptoti...
متن کاملParticle Creation in de Sitter Spacetime and Time Quantization
In this paper,we discussed the particle creation in de Sitter spacetime. When discussing the particle creation in a very short span, in used of the temperature of de Sitter space, We found that we must quantize the time.
متن کاملThe fields of uniformly accelerated charges in de Sitter spacetime.
The scalar and electromagnetic fields of charges uniformly accelerated in de Sitter spacetime are constructed. They represent the generalization of the Born solutions describing fields of two particles with hyperbolic motion in flat spacetime. In the limit Lambda-->0, the Born solutions are retrieved. Since in the de Sitter universe the infinities I+/- are spacelike, the radiative properties of...
متن کاملDecay of charged fields in de Sitter spacetime
We study the decay of charged scalar and spinor fields around Reissner-Nordström black holes in de Sitter spacetime through calculations of quasinormal frequencies of the fields. The influence of the parameters of the black hole (charge, mass), of the decaying fields (charge, spin), and of the spacetime (cosmological constant) on the decay is analyzed. The analytic formula for calculation quasi...
