Dftb torsion
WebMar 13, 2014 · 2. Theoretical approach. DFTB can be derived from a Taylor series expansion of the KS density functional total energy [] around a properly chosen reference density ρ(r).Instead of finding the electron density ρ(r) that minimizes the energy a reference density ρ 0 is assumed which is perturbed by some density fluctuation, ρ(r)=ρ 0 … WebThe DFTB module can treat molecular as well as periodic systems (1D for nanotubes, 2D for surfaces, 3D for bulk), and as such can be used as a fast pre-optimizer for full molecular …
