1. Title:
SIMPLIFIED METHODS OF abinitio CALCULATIONS OF PHYSICAL PROPERTIES OF CRYSTALS
Authors:
N.F. Efremov.



Abstract:
The results of calculations of the electron density, equation of state, and phonon spectrum conducted within the framework of self-consistent and non-self-consistent approaches are compared. The proposed technique of parametrization of the electron density in a crystal significantly shortens the time of calculation of the total energy, electron response, and elastic properties of a crystal. The results of both approaches agree well with experimental data.
