Birefringent Gravitational Waves and the Consistency Check of Inflation
Stephon Alexander, Jerome Martin
In this work we show that the gravitational Chern-Simons term, aside from being a key ingredient in inflationary baryogenesis, modifies super-horizon gravitational waves produced d…
Back-Reaction and the Trans-Planckian Problem of Inflation Revisited
Robert H. Brandenberger, Jerome Martin
It has recently been suggested that Planck scale physics may effect the evolution of cosmological fluctuations in the early stages of cosmological inflation in a non-trivial way, l…
Inflationary Cosmological Perturbations of Quantum-Mechanical Origin
Jerome Martin
This review article aims at presenting the theory of inflation. We first describe the background spacetime behavior during the slow-roll phase and analyze how inflation ends and th…
On the properties of the transition matrix in bouncing cosmologies
Jerome Martin, Patrick Peter
We elaborate further on the evolution properties of cosmological fluctuations through a bounce. We show this evolution to be describable either by ``transmission'' and ``reflection…
Propagating Cosmological Perturbations in a Bouncing Universe
Patrick Peter, Jerome Martin
Using the simplest model for a bouncing universe, namely that for which gravity is described by pure general relativity, the spatial sections are positively curved and the matter c…
