Extra-Dimensional de Broglie-Bohm Quantum Cosmology
F. A. P. Alves-Júnior, A. S. Lemos, F. A. Brito
In this work, we explore the de Broglie-Bohm Quantum Cosmology for a stiff matter, , anisotropic n-dimensional Universe. One begins by considering a Gaussian wave function f…
Intermediate Coupling Regime in Dilatonic Inflationary Universe
Francisco A. Brito, Carlos H. A. B. Borges, Jose A. V. Campos +1
In the present work we study cosmology in dilatonic gravity to address the inflationary phase of the early Universe. As usual, in dilatonic gravity the scalar potential as…
Hunting for extra dimensions in black hole shadows
A. S. Lemos, J. A. V. Campos, F. A. Brito
Observational data of the Sagittarius A* (Sgr A*) shadow released by the Event Horizon Telescope (EHT) are used to investigate eventual deviations in the black hole shadow radius,…
On the initial state of the universe and the time arrow
Carlos Silva, Renan Aragão, Francisco A. Brito
In this paper, we investigate an important issue addressed by several approaches to quantum cosmology, like that based on loop quantum gravity and string theory: the existence of a…
