Ion density fluctuations in liquid metals: the strongly interacting ion-electron plasma
An unified description of liquid metals dynamics based on an interacting two-component model for the ionelectron plasma is tempted. The propagation velocity of the collective modes in alkali and polyvalent metals, derived from inelastic neutron and x-rays scattering experiments, is compared with t...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | An unified description of liquid metals dynamics based on an interacting two-component model for the ionelectron
plasma is tempted. The propagation velocity of the collective modes in alkali and polyvalent metals,
derived from inelastic neutron and x-rays scattering experiments, is compared with the estimates obtained by
different theoretical approximations for the strongly-interacting plasma. Using accurate results for the electron
gas correlation energy, and taking into account the ion finite size effects, a good overall description of a large
set of liquid metals is obtained. The observed trend for the damping of the collective modes in liquid metals is
also discussed within the framework of the two-component description. |
