Inflationary Perturbations

This page has the summary of work done for the final project for Wayne Hu's cosmology class. The project involves calculating the evolution of scalar field perturbation during inflation by solving the exact equation of motion for the scalar field and its perturbation.

The details of the calculations and the results are presented in the web page linked below. The link to the original postscript version of the paper is also available.

Please note that the code is rather undocumented as of now. Also, it's not very user friendly. It should improve soon.
