We apply to secure 2019-2020 computing resources for Chalmers
architects of the van der Waals (vdW) density functional (vdW-DF)
method for truly-nonlocal density functional theory (DFT) calculations.
We apply for a large SNIC allocation because we intend to now launch and
document the first range-separated hybrid based on our strictly nonempirical
spin vdW-DF-cx exchange-correlation (XC) functional. The new range-separated hybrid functional, termed vdW-DF-ahcx, is defined by a formal analysis (completed in an ongoing VR project) of the vdW-DF-cx exchange hole. It is now coded in the Quantum Espresso DFT package with full acceleration for hybrid calculations through ACE. The vdW-DF-ahcx hybrid will be broadly released -- with the generic coding implemented
through our library, termed `libvdwxc' , for highly scalable
vdW-DF calculations -- when we have published a comprehensive testing
and analysis of performance.
