Analytical Hartree-Fock gradients with respect to the cell parameter for systems periodic in three dimensions

Materials Science 2007-05-23 v1

Abstract

Analytical Hartree-Fock gradients with respect to the cell parameter have been implemented in the electronic structure code CRYSTAL, for the case of three-dimensional periodicity. The code is based on Gaussian type orbitals, and the summation of the Coulomb energy is performed with the Ewald method. It is shown that a high accuracy of the cell gradient can be achieved.
