Cosmological models with asymmetric quantum bounces

P. C. M. Delgado, N. Pinto-Neto

In quantum cosmology, one has to select a specific wave function solution of the quantum state equations under consideration in order to obtain concrete results. The simplest choic…

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…

Tensor Perturbations in Quantum Cosmological Backgrounds

Patrick Peter, Emanuel Pinho, Nelson Pinto-Neto

In the description of the dynamics of tensor perturbations on a homogeneous and isotropic background cosmological model, it is well known that a simple Hamiltonian can be obtained…

Quantum gravity correction, evolution of scalar field and inflation

J. Acacio de Barros, N. Pinto-Neto, I. L. Shapiro

We take the first nontrivial coefficient of the Schwinger-DeWitt expansion as a leading correction to the action of the second-derivative metric-dilaton gravity. To fix the ambigui…
