Density functional theory adalah
WebDensity functional theory (DFT) is a quantum-mechanical atomistic simulation method to compute a wide variety of properties of almost any kind of atomic system: molecules, crystals, surfaces, and even electronic devices when combined with non-equilibrium Green's functions (NEGF). WebFeb 11, 2024 · Empirical dispersion accounts for the fact that Density Functional Theory systematically underestimates Van der Waals interactions. DFT-D and DFT-D2 are very simple. DFT-D3 is a bit more complex.

WebJul 15, 2024 · Hohenberg and Kohn established that the ground state energy, E, of interacting electrons in a potential, v ( r), is a functional of the electron density, n ( r): (1) E [ n] = F [ n] + ∫ d r v ( r) n ( r). While this statement is formally true, we do yet not have a convenient way to compute the "universal functional" F [ n] exactly for most cases.
