The Clockwork Standard Model
Yoo-Jin Kang, Soonbin Kim, Hyun Min Lee
We consider various bulk fields with general dilaton couplings in the linear dilaton background in five dimensions as the continuum limit of clockwork models. We show that the loca…
No-boundary wave function for two-field inflation
Dong-il Hwang, Soo A Kim, Dong-han Yeom
In this paper, we investigate the no-boundary wave function and the complex-valued instantons for two-field inflation models that have different masses. If there is a relatively ma…
No-boundary measure and preference for large e-foldings in multi-field inflation
Dong-il Hwang, Soo A Kim, Bum-Hoon Lee +2
The no-boundary wave function of quantum gravity usually assigns only very small probability to long periods of inflation. This was a reason to doubt about the no-boundary wave fun…
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…
