Prerequisite: DFT+U. The tutorial on the calculation of effective interactions U and J by the cRPA method shows how to determine the U value with the constrained Random Phase Approximation using projected Wannier orbitals. A demonstration of how one can use GaussView 5 and Gaussian 09 to perform a density functional theory geometry optimization and harmonic frequency calculation I am interested in exploring the electronic properties of 2D materials (graphene, silicene, MoS2, etc), their van der waal hetero-structures and hybrid structures with DFT (TD-DFT and MD A DFT is a Fourier that transforms a discrete number of samples of a time wave and converts them into a frequency spectrum. However, calculating a DFT is sometimes too slow, because of the number of multiplies required. An FFT is an algorithm that speeds up the calculation of a DFT. In essence, an FFT is a DFT for speed.
