Metal-Dielectric Transition in Hydrogen

Abstract

The electrical resistivity of liquid metallic hydrogen at a temperature of 3000 K and a density of 0.35 mol/cm 3 is calculated. Hydrogen is considered as a three-component system consisting of electrons, protons, and neutral hydrogen atoms. The second order of perturbation theory in electron-proton and electron-atom interactions is used to determine the inverse relaxation time for electric conductivity. The Coulomb electron-electron interaction is taken into account in the random phase approximation and the exchange interaction and correlation of conductivity electrons are included in the local--field approximation. The model of hard spheres is used for the proton and atomic subsystems. The concentration of the electrically neutral atomic component proved to be significantly lower than the value assumed by the discoverers of metallic hydrogen.

“…Оскiльки поведiнка формфакторiв водню i гелiю практично для всiх значень хвильового вектора подiбна, слiд очiкувати такої ж поведiнки щодо збiжностi для рядiв теорiї збурень для рiзних властивостей цих металiв. Цi ряди, зокрема для водню, не дуже близько до точки переходу металдiелектрик, досить добре збiгаються [11][12][13].…”
