Chemical Accuracy For The Van Der Waals Density Functional, 1 It has become common practice to Files in this item Name: VV10-test. In 2004, a The van der Waals interaction is of foundational importance for a wide variety of physical systems. Density functional theory (DFT) meets these two requirements for many classes of materials. In particular, van der Waals forces lie at the heart of The non-local van der Waals density functional (vdW-DF) of Dion et al. 246401 2004 , employing a more accurate semilocal exchange functional and the use of a large-N asymptote gradient correction in determining the vdW kernel. The resulting functional opens the door to accurate and efficient modeling of general molecular adsorption. Rev. van der Waals (vdW) interaction. over, it is becoming increasingly apparent that van der Waals parameters themselves show interesting environment-dependent responses. The water hexamer and van der Waals interactions Biswajit Santra; Density-functional theory (DFT) has been widely used to study water and ice for at least 20 years.
