Analysis of a Fast Fourier Transform Based Method for Modeling of Heterogeneous Materials
Homogenization Fast Fourier Transform Conjugate Gradients
2011/8/18
Abstract: The focus of this paper is on the analysis of the Conjugate Gradient method applied to a non-symmetric system of linear equations, arising from a Fast Fourier Transform-based homogenization ...
Lagrange-mesh calculations and Fourier transform
Lagrange-mesh calculations Fourier transform
2011/9/1
The Lagrange-mesh method is a very accurate procedure to compute eigenvalues and eigenfunctions of a two-body quantum equation. The method requires only the evaluation of the potential at some mesh po...
Gaussian flexibility with Fourier accuracy: the periodic von Neumann basis set
Gaussian flexibility Fourier accuracy Neumann basis set
2010/11/5
We propose a new method for solving quantum mechanical problems, which combines the flexibility of Gaussian basis set methods with the numerical accuracy of the Fourier method. The method is based on ...
