Abstract
We present a comprehensive computational study of the transition from insulator to metal for the inert gases The linearized augmented plane wave LAPW method with the local density approximation LDA and generalized gradient approximation GGA was applied to study these transitions Our calculations of the inert gases determined that the total energy of the fcc structure to be lower than the total energy in the bcc structure This is in agreement with the experimentally verified results of the inert gases We have confirmed that under high enough pressure the inert gases Ar Kr Xe and Rn transition from an insulator to a metal Furthermore using the GaspariGyorffyMcMillan theory of superconductivity we find significant signs of superconductivity for these materials under high pressure
