Three-body forces in the lattice dynamics of beryllium
- 1. Istituto di Fisica and Gruppo Nazionale Struttura della Materia, Universita di Modena, Modena, Italy
Description
We present a first-principles calculation of the lattice dynamics of Be. The dynamical matrix is set up by evaluating the total electron energy up to third order in the electron-ion pseudopotential. In this way we are able to describe the three-body forces, which are essential for reproducing the experimental data.
