Elementary Exvitations in FCC Solid Ortho-Hydrogen,
Abstract
An equation of motion formalism is used to give a nonlinear spin-wave treatment of fcc solid ortho-hydrogen. The elementary excitations in ortho-hydrogen are librational waves, which can be treated in a manner similar to spin-waves in magnetism. The excitation spectrum, long-range order, and ground-state energy are calculated. The spin-wave excitations are found to have a nonvanishing effect on both the long-range order and the ground-state energy. But, because of a large energy gap, the spin-wave theory results deviate only slightly from their molecular field values. (Author)
