Quantum empty Bianchi I spacetime with internal time
Przemyslaw Malkiewicz, Patrick Peter, S. D. P. Vitenti
We discuss the question of time in a Bianchi I quantum cosmology in the framework of singularity avoidance. We show that time parameters fall into two distinct classes, that are su…
Selected Topics in Numerical Methods for Cosmology
Sandro Dias Pinto Vitenti, Mariana Penna-Lima
The large amount of cosmological data already available (and in the near future) makes necessary the development of efficient numerical codes. Many software products have been impl…
Modeling the large-scale power deficit with smooth and discontinuous primordial spectra
Sandro D. P. Vitenti, Patrick Peter, Antony Valentini
We investigate a set of cosmological models for which the primordial power spectrum has a large-scale power deficit. The standard power-law spectrum is subject to long-wavelength m…
