Primordial fluctuations and non-Gaussianities in multi-field DBI inflation
David Langlois, Sebastien Renaux-Petel, Daniele A. Steer +1
We study Dirac-Born-Infeld (DBI) inflation models with multiple scalar fields. We show that the adiabatic and entropy modes propagate with a common effective sound speed and are th…

Perturbations in generalized multi-field inflation
David Langlois, Sébastien Renaux-Petel
We study the linear perturbations of multi-field inflationary models governed by a Lagrangian which is a general function of the scalar fields and of a global kinetic term combinin…
