Quantum-to-classical transition of primordial cosmological perturbations in de Broglie-Bohm quantum theory: the bouncing scenario
N. Pinto-Neto, G. B. Santos, W. Struyve
In a previous work we have exhibited a clear description of the quantum-to-classical transition of cosmological quantum fluctuations in the inflationary scenario using the de Brogl…
Consistent Probabilities in Perfect Fluid Quantum Universes
Clécio R. Bom, Nelson Pinto-Neto, Grasiele B. Santos
Recently it has been claimed that the Wheeler-DeWitt quantization of gravity is unable to avoid cosmological singularities. However, in order to make this assertion, one must speci…
Scalar perturbations in a Friedmann-like metric with non-null Weyl tensor
Grasiele B. Santos, Eduardo Bittencourt, José M. Salim
In a previous work the authors have solved the Einstein equations of General Relativity for a class of metrics with constant spatial curvature, where it was found a non vanishing W…
