Primordial Universe with radiation and Bose-Einstein condensate
F. G. Alvarenga, L. G. Ferreira Filho, R. Fracalossi +5
In this work we derive a scenario {in which} the early universe consists of {radiation fluid} and Bose-Einstein condensate. The possibility of gravitational self-interaction due to…
Dynamics of a perfect fluid through velocity potentials with aplication in quantum cosmology
F. G. Alvarenga, R. Fracalossi, R. G. Furtado +1
We review the Eulerian description of hidrodynamics using Seliger-Whitham's formalism (in classical case) and Schutz's formalism (in relativistic case). In these formalisms, the ve…
Classical and quantum cosmology with two perfect fluids: stiff matter and radiation
F. G. Alvarenga, R. Fracalossi, R. C. Freitas +1
In this work the homogeneous and isotropic Universe of Friedmann-Robertson-Walker is studied in the presence of two fluids: stiff matter and radiation described by the Schutz's for…
