Abstract
Optimization of the short-range correlation function in the Jastrow-Nosanow-Koehler form of trial ground-state wave function for quantum crystals, by functional minimization of the ground-state energy, is proved to result automatically in phonon frequencies which are fully consistent: frequencies defined from the one-phonon excitation energy and from the Gaussian portion of the ground-state wave function are identical.Keywords
