Figure 1
(a) MgO phonon dispersion curves from INS experiments [1] ([17] in the original Letter) are shown as data points and those calculated using a shell lattice dynamical model [2] ([13] in the original Letter) are shown as solid lines. (b) Our analysis of reverse Monte Carlo (RMC) configurations derived from neutron powder diffraction (NPD) data. The filled (open) circles correspond to modes with longitudinal (transverse) character. The lines are guides to the eye; each traces data with similar eigenvectors.Reuse & PermissionsFigure 2
MgO phonon dispersion curves from our analysis of (a) molecular dynamcis (MD) configurations and (b) RMC configurations refined against MD-derived diffraction data. The filled (open) circles correspond to modes with predominantly longitudinal (transverse) character. The lines are guides to the eye; each traces data with similar eigenvectors.Reuse & Permissions
