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…
The Shapes of Dirichlet Defects
Mark Bowick, Antonio De Felice, Mark Trodden
If the vacuum manifold of a field theory has the appropriate topological structure, the theory admits topological structures analogous to the D-branes of string theory, in which de…
Running of the Scalar Spectral Index from Inflationary Models
Daniel J. H. Chung, Gary Shiu, Mark Trodden
The scalar spectral index n is an important parameter describing the nature of primordial density perturbations. Recent data, including that from the WMAP satellite, shows some evi…
Baryogenesis and the New Cosmology
Mark Trodden
In this talk I begin with a brief review of the status of approaches to understanding the origin of the baryon asymmetry of the universe (BAU). I then describe a recent model unify…
