Dense hydrogen is studied in the framework of wave packet simulations. In this semi-quantal method the electrons are represented by wave packets which are suitably parameterized, e.g. Gaussians. The time evolution of the system and the equilibrium properties are obtained with the help of a variational principle and by Monte Carlo sampling, respectively. A transition from a molecular to a metallic state is observed. The wave packets become delocalized and the electrical conductivity increases sharply. The phase diagram is calculated in a wide range of the pressure-density-temperature space. In the transition from the molecular to the metallic state the density increases in agreement with recent reverberating shock wave experiments. © 2009 IOP Publishing Ltd.
