“…This possibility is theoretically confirmed by quantum-mechanical calculations made by the Monte Carlo method [10]. After the impressive breakthrough in the experimental studies of hydrogen in the metallic state, theoretical studies of its various properties in broad ranges of densities and pressures [11,12] become increasingly important. This refers, in particular, to the conditions that are specific to the cores of giant planets in the solar system, namely, Jupiter, Saturn, Uranus, and Neptune.…”

“…This refers, in particular, to the conditions that are specific to the cores of giant planets in the solar system, namely, Jupiter, Saturn, Uranus, and Neptune. The theoretical studies may be strongly encouraged by the fact that the methods for shock compression of the matter that are used in laboratory conditions allow experimentalists to obtain virtually any pressures up to a gigabar range [12].…”

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.

Abstract. Lithium fluoride single crystal window was used for optical light emission registration during quasi-isentropic compression of hydrogen to the pressures 100-150 GPa. Initially gaseous hydrogen samples at 78 K temperature and different pressures in the range 3-30 MPa were investigated. Recorded brightness temperature profiles in near infrared range of wavelength were analyzed to evaluate optical and transport properties of the investigated hydrogen sample and window. Two EOS models of hydrogen, with and without metallic region were used for 1-D simulation of it's properties under dynamic compression and estimation of hydrogen temperature within compressed layer. The obtained data demonstrate abrupt change of final temperatures after heating higher then 3500K.
