The effects of dark energy on the early universe with radiation and Bose-Einstein condensate
G. A. Monerat, F. G. Alvarenga, S. V. B. Gonçalves +4
This work analyzes the effects of quantization on a Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) model with positive curvature and material content composed of a Bose-Einstein cond…
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…
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…
DeBroglie-Bohm interpretation of a Hořava-Lifshitz quantum cosmology model
G. Oliveira-Neto, L. G. Martins, G. A. Monerat +1
In the present letter, we consider the DeBroglie-Bohm interpretation of a Hořava-Lifshitz quantum cosmology model in the presence of a radiation perfect fluid. We compute the Bohm'…
A canonical transformation and the tunneling probability for the birth of an asymptotically DeSitter universe with dust
E. V. Corrêa Silva, G. A. Monerat, G. Oliveira-Neto +2
In the present work, we study the quantum cosmology description of closed Friedmann-Robertson-Walker models in the presence of a positive cosmological constant and a generic perfec…
Reply to "Comment on 'Quantization of FRW spacetimes in the presence of a cosmological constant and radiation'"
N. A. Lemos, G. A. Monerat, E. V. Corrêa Silva +2
The Comment by Amore {\it et al.} [gr-qc/0611029] contains a valid criticism of the numerical precision of the results reported in a recent paper of ours [Phys. Rev. D {\bf 73}, 04…
