15.01.2026 Recently Bruno Ploumhans from our team has been running the virtual oxide verification study by Bosoni et. al. with the density-functional toolkit (DFTK). Our code is now fully included in the interactive results shown on https://acwf-verification.materialscloud.org/. General agreement with other codes is excellent, save a few examples on the bottom right of the periodic table, where we are currently investigating the deviations.
