Anharmonic Lattice Dynamics in Na
where X is the vector potential. The results obtheory developed here and in SP with which the experiments give qualitative verification is ent-'rely based on the assumption that in the presence of a magnetic field, the Hamiltonian for the surfacestate levels is given by the replacement tained here indicate that this approximation remains valid when cubic terms are involved in the band structure,
متن کاملThe effect of alkaline earth metals (Magnesium and Calcium) on Hydrogen storage efficiency of alanate nanopowders
Different Aluminum: alkaline earth metal atomic weight ratios effects on structure transformations in alanates nanopowders were studied. Changes in crystal structures from alane to alanates by increasing alkaline earth metals dopants in the mixture with slight changes in crystal structures from rhombohedral centered – trigonal (alane) to trigonal (magnesium alanate), and monoclinic (calcium ala...

متن کاملAnharmonic lattice dynamics of solid potassium
An intcrionic potential proposed by Dagcns, Rasolt, and Taylor has been used in classical computcrsimulation experiments on solid K at 162.5 and 311 K. Results for the dynamical structure factor S{gre) are compared with lattice-dynamical calculations employing the self-consistent harmonic approximation plus cubic anharmonic corrections. The lattice&ynamical calculations are in good accord with ...
متن کاملNonperturbative anharmonic phenomena in crystal lattice dynamics
Slow dynamics of energy transfer between different phonon modes under the resonance conditions is considered. It may result in new effects in the inelastic and quasielastic neutron scattering spectra.
