Feeding your Inflaton: Non-Gaussian Signatures of Interaction Structure
Neil Barnaby, Sarah Shandera
Primordial non-Gaussianity is generated by interactions of the inflaton field, either self-interactions or couplings to other sectors. These two physically different mechanisms can…
Overproduction of cosmic superstrings
Neil Barnaby, Aaron Berndsen, James M. Cline +1
We show that the naive application of the Kibble mechanism seriously underestimates the initial density of cosmic superstrings that can be formed during the annihilation of D-brane…
Warped Reheating in Brane-Antibrane Inflation
N. Barnaby, C. P. Burgess, J. M. Cline
We examine how reheating occurs after brane-antibrane inflation in warped geometries, such as those which have recently been considered for Type IIB string vacua. We adopt the stan…
Caustic Formation in Tachyon Effective Field Theories
Neil Barnaby
Certain configurations of D-branes, for example wrong dimensional branes or the brane-antibrane system, are unstable to decay. This instability is described by the appearance of a…
