GraPhaRe: Gravitational Waves from Phase Transitions during Reheating

Authors: Manuel A. Buen-Abad, Jae Hyeok Chang, Anson Hook

GraPhaRe

This code has been written in Wolfram language using Mathematica 12.0 by Manuel A. Buen-Abad and Jae Hyeok Chang (2022).

Installing the code

There are two packages: DSReheating.wl, which computes the reheating history of the dark sector; and PhaseTransition.wl, which computes various observables from the first-order phase transition.

To install, simply open a Mathematica notebook and:

1. Go to File -> Install.
2. In the "Source" drop menu, click "From File...".
3. Select the package.
4. Click "OK".

To call the packages, simply enter the following commands in a Mathematica cell:

Needs["DSReheating`"]
Needs["PhaseTransition`"]

Using the code

You can use GraPhaRe freely, provided that in any resulting publications you cite the paper Buen-Abad, Chang, Hook (2023).
