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…
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…
Inflating an Inhomogeneous Universe
Richard Easther, Layne C. Price, Javier Rasero
While cosmological inflation can erase primordial inhomogeneities, it is possible that inflation may not begin in a significantly inhomogeneous universe. This issue is particularly…
The Knotted Sky II: Does BICEP2 require a nontrivial primordial power spectrum?
Kevork N. Abazajian, Grigor Aslanyan, Richard Easther +1
An inflationary gravitational wave background consistent with BICEP2 is difficult to reconcile with a simple power-law spectrum of primordial scalar perturbations. Tensor modes con…
The Knotted Sky I: Planck constraints on the primordial power spectrum
Grigor Aslanyan, Layne C. Price, Kevork N. Abazajian +1
Using the temperature data from Planck we search for departures from a power-law primordial power spectrum, employing Bayesian model-selection and posterior probabilities. We param…
