Electric property of solid hydrogen and magnetoresistivity of tin superhydride

Abstract

We derive the physical mechanisms that deny solid hydrogen to be a metal for any pressure. Fermi- nor strange-metallic phase cannot be achieved in solid hydrogen with applied pressure. The resistance and Raman data indicate insufficient carrier density and large-angle electron-ion scattering induced resistivity in molecular or atomic solid hydrogen. In the absence of Fermi-metallic or strange-metallic phase, solid hydrogen cannot superconduct for any temperature and pressure. Doping hydrogen to form superhydride can lead to low resistivity metallic phase. We show that the resistance and magnetoresistance data for Sn-H superhydride does indicate superconductivity (at high pressures) due to the observed strange normal-state metallic phase with large carrier density. We exploit the Ionization Energy Theory and the low temperature Fermi liquid transport theory to derive the magnetoresistance formula and the magnetic-field induced scattering rate mechanisms to justify the strange metallic phase that obeys Arulsamy fermions and superconductivity in Sn-H.
