Chaplygin inspired Inflation
O. Bertolami, V. Duvvuri
We discuss chaotic inflation in the context of a phenomenological modification of gravity inspired by the Chaplygin gas equation of state. We find that all observationalconstraints…

The Cosmology of Generalized Modified Gravity Models
Sean M. Carroll, Antonio De Felice, Vikram Duvvuri +3
We consider general curvature-invariant modifications of the Einstein-Hilbert action that become important only in regions of extremely low space-time curvature. We investigate the…

Is Cosmic Speed-Up Due to New Gravitational Physics?
Sean M. Carroll, Vikram Duvvuri, Mark Trodden +1
We show that cosmic acceleration can arise due to very tiny corrections to the usual gravitational action of General Relativity of the form , with . This eliminates the n…
