Quantum cosmological perturbations in bouncing models with mimetic dark matter
Idaiane L. Machado, Dêivid R. da Silva, Nelson Pinto-Neto
We calculate the power spectrum of cosmological perturbations originated from quantum vacuum fluctuations in bouncing scenarios proposed in Ref.~\cite{chamseddine2014cosmology} in…
Bouncing completion of eternal inflation
Alexsandre L. Ferreira, Nelson Pinto-Neto, Vanessa N. Xavier
Using a purely kinematical argument, the Borde-Guth-Vilenkin (BGV) theorem states that any maximal space-time with average positive expansion is geodesically incomplete, hence past…
Dynamical analysis of quantum matter bounces with dark sector mimickers
Francisco Bento Lustosa, Nelson Pinto-Neto
We study the effects of the inclusion of fluids In bounce scenarios driven by an exponential potential scalar field. Most solutions exhibit well known tracking behavior between the…
