Dft-based approach
Density-functional theory (DFT) is a computational quantum mechanical modelling method used in physics, chemistry and materials science to investigate the electronic structure (or nuclear structure) (principally the ground state) of many-body systems, in particular atoms, molecules, and the … See more In the context of computational materials science, ab initio (from first principles) DFT calculations allow the prediction and calculation of material behavior on the basis of quantum mechanical considerations, … See more As usual in many-body electronic structure calculations, the nuclei of the treated molecules or clusters are seen as fixed (the Born–Oppenheimer approximation), generating a static … See more The major problem with DFT is that the exact functionals for exchange and correlation are not known, except for the free-electron gas. … See more In general, density functional theory finds increasingly broad application in chemistry and materials science for the interpretation and prediction of … See more The same theorems can be proven in the case of relativistic electrons, thereby providing generalization of DFT for the relativistic case. … See more The DFT formalism described above breaks down, to various degrees, in the presence of a vector potential, i.e. a magnetic field. … See more The predecessor to density functional theory was the Thomas–Fermi model, developed independently by both Llewellyn Thomas and Enrico Fermi in 1927. They used a statistical … See more WebBoth the DFT-based approaches reproduce trends in the D tensors. Significantly, the differences between the theoretical and experimental D (D = D ZZ − (D XX + D YY)/2) values are smaller in NOB-PK than in PK, …

WebMar 27, 2024 · DFT-based NMR calculations have seen a rapid expansion during the last 10 years—that is perhaps best designated with the word explosion. Since the publication of these calculations, methods have … The DFT has seen wide usage across a large number of fields; we only sketch a few examples below (see also the references at the end). All applications of the DFT depend crucially on the availability of a fast algorithm to compute discrete Fourier transforms and their inverses, a fast Fourier transform. When the DFT is used for signal spectral analysis, the sequence usually repres…

WebDec 28, 2024 · FFT based approaches in micromechanics were first proposed for computational homogenization in the seminal paper (Moulinec and Suquet 1994 ). This original method, called the basic scheme, was a breakthrough because before that moment almost all the numerical micromechanical approaches were based on the FE method.
