FieldInf: an exact solver for linear cosmological perturbations during inflation

---

Summary

This package compiles and install FieldInf, a collection of fast modern fortran routines for integrating, out of any approximations, linear cosmological perturbations during inflation.

As such, it provides an exact integration of the primordial power spectra, computed in a way which is consistent with the reheating, as well as various other background and perturbed quantities (check out the two example programs provided). Moreover, it supports libaspic and you can compare slow-roll versus exact predictions.

Installation

The code is released as GNU software, you are free and welcome to improve this code and distribute the source code along the rules specified in COPYING.

Compilation and installation of the FieldInf library

   ./configure
   make
   make install

Support for libaspic is provided by appending its installation path to the configure script:

   ./configure --with-aspic=/usr/local
   make
   make install

See INSTALL for more options.

Compilation of the tutorial programs (fieldmain and gurumain):

   ./configure
   make check

A basic and easily editable makefile is provided in the "src/" directory to fastly compile the example programs locally:

   make -f Makefile_noauto
