Reply to "Bouncing Universes and their perturbations: remarks on a toy model"
Jerome Martin, Patrick Peter
In this web note, we reply to a recent paper, gr-qc/0404126, confirming a previous work of ours in which a cosmological bouncing phase was shown to have the ability of modifying th…
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…
Perturbations in the Ekpyrotic Scenarios
Patrick Peter, Jerome Martin, Nelson Pinto-Neto +1
With the new cosmological data gathered over the last few years, the inflationary paradigm has seen its predictions largely unchallenged. A recent proposal, called the ekpyrotic sc…
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…
