MultiModeCode: An efficient numerical solver for multifield inflation
Layne C. Price, Jonathan Frazer, Jiajun Xu +2
We present MultiModeCode, a Fortran 95/2000 package for the numerical exploration of multifield inflation models. This program facilitates efficient Monte Carlo sampling of prior p…
The curvature perturbation at second order
Mafalda Dias, Joseph Elliston, Jonathan Frazer +2
We give an explicit relation, up to second-order terms, between scalar-field fluctuations defined on spatially-flat slices and the curvature perturbation on uniform-density slices.…
Gravitational wave consistency relations for multifield inflation
Layne C. Price, Hiranya V. Peiris, Jonathan Frazer +1
We study the tensor spectral index and the tensor-to-scalar ratio in the simplest multifield extension to single-field, slow-roll inflation models. We show that multifiel…
A New Angle on Chaotic Inflation
Thomas C. Bachlechner, Mafalda Dias, Jonathan Frazer +1
N-flation is a radiatively stable scenario for chaotic inflation in which the displacements of axions with decay constants lead to a super-…
