Large classical universes emerging from quantum cosmology
Nelson Pinto-Neto
It is generally believed that one cannot obtain a large Universe from quantum cosmological models without an inflationary phase in the classical expanding era because the typical s…

Scalar Perturbations in Scalar Field Quantum Cosmology
F. T. Falciano, N. Pinto-Neto
In this paper it is shown how to obtain the simplest equations for the Mukhanov-Sasaki variables describing quantum linear scalar perturbations in the case of scalar fields without…

Cold black holes and conformal continuations
K. A. Bronnikov, M. S. Chernakova, J. C. Fabris +2
We study Einstein gravity minimally coupled to a scalar field in a static, spherically symmetric space-time in four dimensions. Black hole solutions are shown to exist for a phanto…
