Resonances in the early Universe
D. L. Canedo, G. Oliveira-Neto, G. A. Monerat +1
In the present paper, we study a Friedmann-Lemaître-Robertson-Walker (FLRW) quantum cosmology model with positively curved spatial sections. The matter content of the model is give…
Quantum Creation of a FRW Universe: applying the Riesz fractional derivative
D. L. Canedo, P. Moniz, G. Oliveira-Neto
In this work, we apply fractional calculus to study quantum cosmology. Specifically, our Wheeler-DeWitt equation includes a FRW geometry, a radiation fluid, a positive cosmological…
Tunneling probability for the birth of universes with radiation, cosmological constant and an ad hoc potential
G. Oliveira-Neto, D. L. Canedo, G. A. Monerat
In this work we study the birth of Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) models with zero () and negative () curvatures of the spatial sections. The material cont…
An anisotropic Kantowski-Sachs universe with radiation, dust and a phantom fluid
G. Oliveira-Neto, D. L. Canedo, G. A. Monerat
In the present work, we study the dynamical evolution of an homogeneous and anisotropic KS cosmological model, considering general relativity as the gravitational theory, such that…
