Data for reproducibility of the numerical simulations of the research paper "Fully guaranteed and computable error bounds on the energy for periodic Kohn-Sham equations with convex density functionals". The .zip file contains everything needed to generate the plots shown in the paper, as well as the code to run your own simulations with the bounds derived in the paper, using the Julia software DFTK.jl.
You just have to extract the tar file from this repository to access the files and the associated README.md.
