Theoretical Magnon Dispersion Curves for Gd

Physical Review Letters, 1975
The magnon dispersion curve of Gd metal has been determined from first principles by use of augmented-plane-wave energy bands and wave functions. The exchange matrix elements $I(\stackrel{\ensuremath{\rightarrow}}{\mathrm{k}}, {\stackrel{\ensuremath{\rightarrow}}{\mathrm{k}}}^{\ensuremath{'}})$ between the $4f$ electrons and the conduction electrons ...

Phonon dispersion curves for palladium

Journal of Physics F: Metal Physics, 1980
A previously proposed six-parameter phenomenological screened shell model is applied to the calculation of the phonon dispersion curves of palladium. The resulting fit, for all symmetric branches except the (111)T, is as good as or better than a seven-parameter calculation using Krebs' model (1965) extended to include two-body forces to third ...

Dispersion relations in graphite intercalation compounds: Phonon dispersion curves

Physical Review B, 1981
A phenomenological model based on staging periodicity and in-plane superlattice symmetry is developed for the phonon dispersion relations of graphite intercalation compounds, analogous to the formalism developed for the electronic dispersion relations. The formalism, based on the zone folding of the graphite dynamical matrix required by symmetry, gives

Spatially Varying Dispersion to Model Breakthrough Curves

Groundwater, 2010
Often the water flowing in a karst conduit is a combination of contaminated water entering at a sinkhole and cleaner water released from the limestone matrix. Transport processes in the conduit are controlled by advection, mixing (dilution and dispersion), and retention‐release.

Interatomic Forces and Phonon Dispersion Curves

1982
Phonon dispersion curves ω(\(\vec q\)) can be measured by inelastic neutron scattering techniques; this important method will be discussed in [1.35]. The curves determined by experiments are mainly of interest because they provide chance of testing various models of interatomic forces.
