Constraints on Kinetically Modified Inflation from WMAP5
Larissa Lorenz, Jerome Martin, Christophe Ringeval
Single field inflationary models with a non-minimal kinetic term (also called k-inflationary models) can be characterised by the so-called sound flow functions, which complete the…
Inflation and Precision Cosmology
Jerome Martin
A brief review of inflation is presented. After having demonstrated the generality of the inflationary mechanism, the emphasize is put on its simplest realization, namely the singl…
Quintessence and the accelerating universe
Philippe Brax, Jerome Martin
Observations seem to indicate that our universe is presently accelerating due to the presence of dark energy. Quintessence represents a possible way to model the dark energy. In th…
Non-vacuum initial states for the cosmological perturbations and the back-reaction problem of inflation
Alejandro Gangui, Jerome Martin, Mairi Sakellariadou
In the framework of Inflationary theory, the assumption that the quantum state of the perturbations is a non-vacuum state leads to a difficulty: non-vacuum initial states imply, in…
A Cosmological Window on Trans-Planckian Physics
Jerome Martin, Robert H. Brandenberger
In the framework of inflation, scales which nowadays correspond to large scale structures were smaller than the Planck length at the beginning of inflation. Therefore, measurements…
High Energy Physics and Quintessence
Philippe Brax, Jerome Martin
It is shown that any realistic model of quintessence should be based on Supergravity (SUGRA) since the value of the quintessence field on the attractor is approximately the Planck…
