✦ Synopsis
Recent multiple-shock experiments of hydrogen at very high pressures show a transition from nonconducting to metallic behaviour at about 140 GPa and a temperature of approximately 3000 K [l].
We simulate hydrogen at various densities and temperatures in the region of this transition. As a theoretical tool we employ "Wave Packet Molecular Dynamics" simulations. This method was originally used by Heller for a description of the scattering of composite particles like simple atoms and molecules [2]; later it was applied to Coulomb systems by Klakow et al. [3]. From the simulations we can extract M.
