Slow-Roll Inflation in the Presence of a Dark Energy Coupling
Philippe Brax, Carsten van de Bruck, Lisa M. H. Hall +1
In models of coupled dark energy, in which a dark energy scalar field couples to other matter components, it is natural to expect a coupling to the inflaton as well. We explore the…

f(R) Gravity and Chameleon Theories
Philippe Brax, Carsten van de Bruck, Anne-Christine Davis +1
We analyse f(R) modifications of Einstein's gravity as dark energy models in the light of their connection with chameleon theories. Formulated as scalar-tensor theories, the f(R) t…
