Primordial curvature perturbation during and at the end of multi-field inflation
Ki-Young Choi, Soo A Kim, Bumseok Kyae
We study the generation of the primordial curvature perturbation in multi-field inflation. Considering both the evolution of the perturbation during inflation and the effects gener…

Non-gaussianity in axion N-flation models: detailed predictions and mass spectra
Soo A Kim, Andrew R Liddle, David Seery
We have recently shown that multi-field axion N-flation can lead to observable non-gaussianity in much of its parameter range, with the assisted inflation mechanism ensuring that t…

Non-gaussianity in axion Nflation models
Soo A Kim, Andrew R Liddle, David Seery
We study perturbations in the multi-field axion Nflation model, taking account of the full cosine potential. We find significant differences with previous analyses which made a qua…
