WebJan 5, 2024 · The most recent and important development in DFTB is the long-range corrected DFTB (LC-DFTB). The first two practical implementation and benchmark studies were reported in 2015 by Humeniuk et al. [ 27 ] and Lutsker et al. [ 28 ], although the initial formulation was outlined in 2012 by a coauthor of the latter study [ 29 ]. WebDFTB Manual 2024.1. The DFTB engine implements Density Functional based Tight-Binding methods, which can be viewed as computationally very efficient approximations to density functional theory (DFT). As such it is a good engine for computationally fast calculations that still include quantum effects. It can be used for molecules and for …
