Ghost Inflation
Nima Arkani-Hamed, Paolo Creminelli, Shinji Mukohyama +1
We propose a new scenario for early cosmology, where an inflationary de Sitter phase is obtained with a ghost condensate. The transition to radiation dominance is triggered by the…
On non-gaussianities in single-field inflation
Paolo Creminelli
We study the impact of higher dimension operators in the inflaton Lagrangian on the non-gaussianity of the scalar spectrum. These terms can strongly enhance the effect without spoi…
Pseudonatural Inflation
Nima Arkani-Hamed, Hsin-Chia Cheng, Paolo Creminelli +1
We study how to obtain a sufficiently flat inflaton potential that is natural from the particle physics point of view. Supersymmetry, which is broken during inflation, cannot prote…
Extranatural Inflation
Nima Arkani-Hamed, Hsin-Chia Cheng, Paolo Creminelli +1
We present a new model of inflation in which the inflaton is the extra component of a gauge field in a 5d theory compactified on a circle. The chief merit of this model is that the…
