Quantum Cosmology with many fluids and the choice of cosmological time
G. A. Monerat, C. G. M. Santos, F. G. Alvarenga +4
In this work we propose the quantization of a cosmological model describing the primordial universe filled with five barotropic fluids, namely: radiation, dust, vacuum, cosmic stri…
Noncommutative cosmological models induced by a symplectic formalism coupled to phantom fluids
G. Oliveira-Neto, L. G. Rezende Rodrigues
In the present letter, we consider homogeneous and isotropic noncommutative cosmological models induced by a symplectic formalism coupled to phantom perfect fluids and a cosmologic…
Quantum cosmology of a Hořava-Lifshitz model coupled to radiation
G. Oliveira-Neto, L. G. Martins, G. A. Monerat +1
In the present paper, we canonically quantize an homogeneous and isotropic Hořava-Lifshitz cosmological model, with constant positive spatial sections and coupled to radiation. We…
