Python tool for the computation and tabulation of atomic response functions for direct sub-GeV dark matter (DM) searches.

• This code computes the four atomic response functions introduced in the paper [arXiv:1912.08204].
• The tabulation of the atomic response functions is separated into two steps:
  • the computation and tabulation of three radial integrals (via /src/radial_integrals_tabulation.py).
  • their combination into the response function tables (via /src/atomic_responses_tabulation.py).
• The computations are performed in parallel using the multiprocessing library.

The included folders are:

• /data/: Destination folder of the code's output (tables of integration methods, radial integrals, and finally atomic response functions).
• /src/: Contains the source code.
