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…

Cosmological perturbations during the Bose-Einstein condensation of dark matter
R. C. Freitas, S. V. B. Gonçalves
In the present work, we analyze the evolution of the scalar and tensorial perturbations and the quantities relevant for the physical description of the Universe, as the density con…
