We apply to secure 12 months of 2021 computing resources (as well as storage) for the research programs of Chalmers architects of the van der Waals (vdW) density functional (vdW-DF) method for truly-nonlocal density functional theory (DFT) calculations. We apply to continue our present (12 month) large computation SNIC2019-2-19 (and medium storage SNIC2019-35-67) grants to broaden our launch and demonstration of the first range-separated nonlocal-correlation hybrids, termed vdW-DF-ahcx and vdW-DF2-ahbr. The overall goal is to seek a better theoretical understanding of DNA, of weak chemisorption of organics (including polymers), of (potentially) soft modes and phase transitions in oxides, in polymers, in magnetic and hybrid-organic-oxide ferroelectrics, and to map the anharmonic dynamics of peptides for understanding optical-response measurements. To that end we propose that a wider set of documentation projects joins the ongoing method launch.
