Expanding and Contracting Universes in Third Quantized String Cosmology
We discuss the possibility of quantum transitions from the string perturbative vacuum to cosmological configurations characterized by isotropic contraction and decreasing dilaton. When the dilaton potential preserves the sign of the Hubble factor throughout the evolution, such transitions can be represented as an anti-tunnelling of the Wheeler–De Witt wave function in minisuperspace or, in a th...

متن کاملScale-invariance in expanding and contracting universes from two-field models
We study cosmological perturbations produced by the most general twoderivative actions involving two scalar fields, coupled to Einstein gravity, with an arbitrary field space metric, that admit scaling solutions. For expanding universes, we find that scaleinvariant adiabatic perturbation spectra can be produced for any equation of state parameter w that satisfies −1 ≤ w < −1/3, and that all the...
متن کاملDisks in Expanding FRW Universes
We construct exact solutions to Einstein equations which represent relativistic disks imbedded in an expanding FRW Universe. It is shown that the expansion influences the kinematical characteristics of the disks such as rotational curves, surface mass density, etc. The effects of the expansion are exemplified with non-static generalizations of Kuzmin-Curzon and Schwarzschild disks. Subject head...
متن کاملEntanglement Structure in Expanding Universes
We investigate entanglement of a quantum field in de Sitter spacetime using a particle detector model. By considering the entanglement between two comoving detectors interacting with a scalar field, it is possible to detect the entanglement of the scalar field by swapping it to detectors. For the massless minimal scalar field, we find that the entanglement between the detectors cannot be detect...
