Inflation.jl -- A Julia package for numerical evaluation of cosmic inflation models using the transport method

  • 1. University of Texas at Austin

Description

A Julia package for numerical evaluation of cosmic inflation models. Perturbations are evolved with the transport method. It supports symbolic calculation of the equations of motion, and remains efficient at a high number of fields, even with non-canonical kinetic terms.

Inflation.jl automatically applies the horizon-crossing approximation, if the potential is detected to be sum-separable. Support is planned for automatic application of other approximations when they are valid as well, as well as automatic calculation of stochastic gravitational wave backgrounds and their estimated SNR in LISA and PTA scales.
