A Back-reaction Induced Lower Bound on the Tensor-to-Scalar Ratio
P. Martineau, R. Brandenberger
There are large classes of inflationary models, particularly popular in the context of string theory and brane world approaches to inflation, in which the ratio of linearized tenso…

Back-Reaction: A Cosmological Panacea
P. Martineau, R. Brandenberger
We present a solution to the dark energy problem in terms of the Effective Energy Momentum Tensor (EMT) of cosmological perturbations. The approach makes use of the gravitational b…

The Effects of Gravitational Back-Reaction on Cosmological Perturbations
Patrick Martineau, Robert Brandenberger
Because of the non-linearity of the Einstein equations, the cosmological fluctuations which are generated during inflation on a wide range of wavelengths do not evolve independentl…
