BOSSANOVA: A bond order dissection approach for efficient electronic structure calculations
(2008-01)
In this article, we present a new decomposition approach for the eff cient approximate calculation of the electronic structure problem for molecules. It is based on a dimension-wise decomposition of the space the underlying ......
Multiscale simulation of ion migration for battery systems
(2012-11)
In this paper we describe a multi-scale approach to ion migration processes, which involves a bridging from the atomic scale to the macroscopic scale. To this end, the diffusion coefficient of a material i.e. a macroscopic ...
A molecular dynamics study of cementitious calcium silicate hydrate (C-S-H) gels
(2007-05)
In this article we study the polymerization of silicic acids (Si(OH)4) in the presence of calcium ions by molecular dynamics simulations. We focus on the formation and structure of cementitious calcium silicate ...
Fast discrete Fourier transform on generalized sparse grids
(2013-03)
In this paper, we present an algorithm for trigonometric interpolation of multivariate functions on generalized sparse grids and study its application for the approximation of functions in periodic Sobolev spaces of ...
Sparse grids for the Schrödinger equation
(2005-12)
We present a sparse grid/hyperbolic cross discretization for many-particle problems. It involves the tensor product of a one-particle multilevel basis. Subsequent truncation of the associated series expansion then results ...
A bond order dissection ANOVA approach for efficient electronic structure calculations
(2014-03)
In this article, we present a new decomposition approach for the efficient approximate calculation of the electronic structure problem for molecules. It is based on a dimension-wise decomposition of the space the underlying ......
An adaptive multiscale approach for electronic structure methods
(2016)
In this paper, we introduce a new scheme for the efficient numerical treatment of the electronic Schr¨odinger equation for molecules. It is based on the combination of a many-body expansion, which corresponds to the bond ...
Molecular dynamics simulations of the influence of chemical cross-links on the elastic moduli of polymer-carbon nanotube composites
(2005-06)
In this article we compare the Young modulus of polyethylene carbon nanotube composites with chemical cross-links between the nanotube and the polyethylene matrix to the modulus of a composite with weak non-bonded ...
A wavelet based sparse grid method for the electronic Schrödinger equation
(2006-05)
We present a direct discretization of the electronic Schrödinger equation. It is based on one-dimensional Meyer wavelets from which we build an anisotropic multiresolution analysis for general particle spaces by a tensor ...
