Inflationary predictions in scalar-tensor DBI inflation
Joel M. Weller, Carsten van de Bruck, David F. Mota
The scalar-tensor Dirac-Born-Infeld (DBI) inflation scenario provides a simple mechanism to reduce the large values of the boost factor associated with single field models with DBI…
Embedding DBI inflation in scalar-tensor theory
Carsten van de Bruck, David F. Mota, Joel M. Weller
The Dirac-Born-Infeld (DBI) action has been widely studied as an interesting example of a model of k-inflation in which the sound speed of the cosmological perturbations differs fr…
Quintessence dynamics with two scalar fields and mixed kinetic terms
Carsten van de Bruck, Joel M. Weller
The dynamical properties of a model of dark energy in which two scalar fields are coupled by a non-canonical kinetic term are studied. We show that overall the addition of the coup…
