A pilot study on canonical gravity with mass dimension one fermions
R. de C. Lima, T. M. Guimarães, S. H. Pereira
The mass dimension one (MDO) fermionic field is built on a complete set of dual-helicity eigenspinors of the charge conjugation operator, which obeys the statistic of Fermi-Dirac.…
Cosmological inflation driven by a scalar torsion function
T. M. Guimarães, R. de C. Lima, S. H. Pereira
A viable model for inflation driven by a torsion function in a Friedmann background is presented. The scalar spectral index in the interval is obt…
An unified cosmological evolution driven by a mass dimension one fermionic field
S. H. Pereira, M. E. S. Alves, T. M. Guimarães
An unified cosmological model for an Universe filled with a mass dimension one (MDO) fermionic field plus the standard matter fields is considered. After a primordial quantum fluct…
From inflation to recent cosmic acceleration: The fermionic Elko field driving the evolution of the universe
S. H. Pereira, T. M. Guimarães
In this paper we construct the complete evolution of the universe driven by the mass dimension one dark spinor called Elko, starting with inflation, passing by the matter dominated…
