DFTB is an approximate method, and as such shows limitations, which can be traced back to the different approximations applied. However, the fitting of Eq. can compensate for some of the inaccuracies. Since until now, only bonding contributions are addressed by the two-center nature of the repulsive potentials, bond-lengths, bond-stretch

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 systems of any periodicity

Introduction#. This document is a collection of examples demonstrating the usage of the atomistic quantum mechanical software DFTB+.. Before you start#. The examples assume that you have the latest stable version of DFTB+ installed (although many of the recipes may also work with older versions of the code). Additionally the examples require some parameterisation files (Slater-Koster files

Density functional tight binding (DFTB) is an approximate density functional based quantum chemical simulation method with low computational cost. In order to increase its accuracy, we have introduced a machine learning algorithm to optimize several parameters of the DFTB method, concentrating on solids with defects.

In DFTB it originates naturally and inevitably from Eq. (48), because non-overlapping orbitals with diagonal overlap matrix would yield also diagonal Hamiltonian matrix, which would mean chemically non-interacting system. The transferability of a tight-binding model is often attributed to non-orthogonality, because it accounts for the spatial
