2-point functions in curved field-space


3DfeaturePyTransport and CppTransport currently do not support inflation models with a non-trivial field-space metric.

mTransport is implemented in Mathematica and computes the two-point correlation function of the curvature and tensor perturbations with an arbitrary field-space metric and scalar potential. It retains all the other benefits of the transport framework including accommodation of arbitrary mass hierarchies.

The code is designed to be simple and easy to follow, and should be useful for anyone interested in computing observables related to the power spectrum of curvature and tensor perturbations in non-canonical multiple-field models.
