Two-bubble simulation and gravitational wave spectrum codes and data

Code and data used in the paper with title Vacuum bubble collisions: from microphysics to gravitational waves by Oliver Gould, Satumaaria Sukuvaara, and David Weir [arXiv:2107.05657]. 

The field simulation and gravitational wave spectrum calculation codes are based on Gravitational radiation from colliding vacuum bubbles by Arthur Kosowsky, Michael S. Turner and Richard Watkins [Inspire].

Contains files:

• two_bubbles_code-v1.0.1.zip is a snapshot of a git repository, corresponding to commit v1.0.1. Contains the codes with which the majority of the data was produced.
  
  

• two_bubbles_data-v1.0.1.zip is a snapshot of a git repository, corresponding to commit v1.0.1. It contains the majority of data used in the paper. Note however that the simulation pickle files are examples run on a coarser lattice due to Zenodo file size restrictions. Apart from few exceptions, the data in this file was produced by the codes in two_bubbles_code-v1.0.1.zip.
  
  

README.md files, specifying and explaining the contents and usage, are included within. The v1.0.1 of code README.md and the data README.md can be found from the repositories as well.

The update v1.0.1 updates the README and fixes a small error in the calculation of the gravitational wave spectrum. We thank Toby Opferkuch for pointing this out. The error in the code does not affect the results in two_bubbles_data-v1.0.0.zip or the paper as they were produced with a slightly earlier version of the code, before the appearance of this error. The version two_bubbles_data-v1.0.1 updates the README, clarifying some points.
