Quantization of Scalar Fields in Curved Background and Quantum Algebras
We show that a suitable deformation of the algebra hk(1) of the creation and annihilation operators for a complex scalar field, initially quantized in Minkowski space–time, induces the canonical quantization of the same field in a generic gravitational background. This discloses the physical meaning of the deformation parameter q which turns out to be related to the gravitational field. The the...
متن کاملQuantization of scalar fields in curved background , deformed Hopf algebra and entanglement
A suitable deformation of the Hopf algebra of the creation and annihilation operators for a complex scalar field, initially quantized in Minkowski space–time, induces the canonical quantization of the same field in a generic gravitational background. The deformation parameter q turns out to be related to the gravitational field. The entanglement of the quantum vacuum appears to be robust agains...
متن کاملStochastic 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 کاملAsymptotic tails of massive scalar fields in Schwarzschild background
We investigate the asymptotic tail behavior of massive scalar fields in Schwarzschild background. It is shown that the oscillatory tail of the scalar field has the decay rate of t−5/6 at asymptotically late times, and the oscillation with the period 2π/m for the field mass m is modulated by the long-term phase shift. These behaviors are qualitatively similar to those found in nearly extreme Rei...
