Cosmic acceleration from interaction of ordinary fluids
Nelson Pinto-Neto, Bernardo M. O. Fraga
Cosmological models with two interacting fluids, each satisfying the strong energy condition, are studied in the framework of classical General Relativity. If the interactions are…
Spectra of primordial fluctuations in two-perfect-fluid regular bounces
F. Finelli, P. Peter, N. Pinto-Neto
We introduce analytic solutions for a class of two components bouncing models, where the bounce is triggered by a negative energy density perfect fluid. The equation of state of th…
An Inflationary Non-singular Quantum Cosmological Model
Felipe T. Falciano, Nelson Pinto-Neto, E. Sergio Santini
A stiff matter-dominated universe modeled by a free massless scalar field minimally coupled to gravity in a Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) geometry is quantized. Gene…
