Adiabatic renormalization in theories with modified dispersion relations
D. Lopez Nacir, F. D. Mazzitelli, C. Simeone
We generalize the adiabatic renormalization to theories with dispersion relations modified at energies higher than a new scale . We obtain explicit expressions for the mean va…
Renormalized Stress Tensor for trans-Planckian Cosmology
D. Lopez Nacir, F. D. Mazzitelli, C. Simeone
Finite expressions for the mean value of the stress tensor corresponding to a scalar field with a generalized dispersion relation in a Friedman--Robertson--Walker universe are obta…
Decoherence during Inflation: the generation of classical inhomogeneities
Fernando C. Lombardo, Diana Lopez Nacir
We show how the quantum to classical transition of the cosmological fluctuations produced during inflation can be described by means of the influence functional and the master equa…
