Cosmological Fluctuations from Infra-Red Cascading During Inflation
Neil Barnaby, Zhiqi Huang, Lev Kofman +1
We propose a qualitatively new mechanism for generating cosmological fluctuations from inflation. The non-equilibrium excitation of interacting scalar fields often evolves into inf…

Dynamics and Stability of Light-Like Tachyon Condensation
Neil Barnaby, David J. Mulryne, Nelson J. Nunes +1
Recently, Hellerman and Schnabl considered the dynamics of unstable D-branes in the background of a linear dilaton. Remarkably, they were able to construct light-like tachyon solut…

Nongaussianity from Tachyonic Preheating in Hybrid Inflation
Neil Barnaby, James M. Cline
In a previous work we showed that large nongaussianities and nonscale-invariant distortions in the CMB power spectrum can be generated in hybrid inflation models, due to the contri…
