Computing observables in curved multifield models of inflation — a guide (with code) to the transport method
journal contribution
posted on 2023-06-09, 00:17 authored by Mafalda Dias, Jonathan Frazer, David SeeryDavid SeeryWe describe how to apply the transport method to compute inflationary observables in a broad range of multiple-field models. The method is efficient and encompasses scenarios with curved field-space metrics, violations of slow-roll conditions and turns of the trajectory in field space. It can be used for an arbitrary mass spectrum, including massive modes and models with quasi-single-field dynamics. In this note we focus on practical issues. It is accompanied by a Mathematica code which can be used to explore suitable models, or as a basis for further development.
