The Effective Field Theory of Large Scale Structures

Public code repository


This page provides links to codes that perform various calculations related to the Effective Field Theory of Large Scale Structures (EFTofLSS). If you have any questions or comments, please contact the authors of each code. If you would like your code to be listed on this page, please contact Leonardo Senatore (senatore"AT"stanford"DOT"edu). NB: A great amount of work went in the development of the theory and the first computations associated to the codes we provide below. Therefore, we would be grateful if the papers that are recommended for each code were properly acknowledged.


CosmoEFT

Current version: 1.0 (June 2016)

CosmoEFT is a C++ code to calculate (in a few minutes on laptops) the loop integrals and counterterms involved in the two-loop EFTofLSS prediction for the matter power spectrum. The assembled power spectrum reaches sub-percent accuracy up to mildly nonlinear scales. The code is described in arXiv:1606.03633.

ResumEFT

Current version: 1.0 (June 2016)

ResumEFT is a companion code for CosmoEFT, written in C++, which applies the IR-resummation procedure described in arXiv:1404.5954 and arXiv:1406.4143 to the loop integrals and counterterms computed by CosmoEFT. Output is obtained within a few seconds on laptops. Instructions for use and references to be acknowledged are included in a readme file. Click on the link below to download the code.

TaylorEFT

Current version: 1.0 (June 2016)

TaylorEFT is a Mathematica notebook that swiftly reads off the two-loop matter power spectrum predictions thanks to a Taylor expansion of the EFTofLSS terms around the Planck 2015 best-fit cosmology. It guarantees 1% precision for cosmologies as far as 3-sigma from the reference cosmology over the entire range of scales up to the quasi-linear regime. Also this code is described in arXiv:1606.03633. Instructions for use, as well as papers to be acknowledged, are included in a readme file. Click on the link below to download the code.

RedshiftBiasEFT

Current version: 1.0 (Oct 2016)

RedshiftBiasEFT is a Mathematica code that computes the EFTofLSS prediction for the one-loop power spectrum of biased tracers in redshift space, and performs the IR-resummation in redshift space. This is the code developed to obtain the results in arXiv:1610.09321. The IR-resummation code is the one developed in arXiv:1512.06831 . The IR-resummed power spectrum of biased tracers in real space is also computed, and the power spectrum for dark matter can be obtained by setting the bias parameters to the appropriate values of zero or one. Instructions for use and references to be acknowledged are included in a readme file. Click on the link below to download the code.
