Quantum slow-roll and quantum fast-roll inflationary initial conditions: CMB quadrupole suppression and further effects on the low CMB multipoles
F. J. Cao, H. J. de Vega, N. G. Sanchez
Quantum fast-roll initial conditions for the inflaton which are different from the classical fast-roll conditions and from the quantum slow-roll conditions can lead to inflation th…

The dark matter transfer function: free streaming, particle statistics and memory of gravitational clustering
D. Boyanovsky, H. J. de Vega, N. Sanchez
The transfer function of dark matter (DM) perturbations during matter domination is obtained by solving the collisionless Boltzmann-Vlasov equation. We find an \emph{exact}…

The CMB Quadrupole depression produced by early fast-roll inflation: MCMC analysis of WMAP and SDSS data
C. Destri, H. J. de Vega, N. G. Sanchez
Generically,the classical evolution of the inflaton has a brief fast roll stage that precedes the slow roll regime. The fast roll stage leads to a purely attractive potential for t…
