Ztschr %O Rostock, Univ., Mathematisch-Naturwiss. Fak., Diss., 2012 %X Results from extensive abinitio calculations for hydrogen, helium and their mixtures at high pressures are reported. For H, special attention has been paid to the nonmetal-to-metal-transition and its accompanying first-order liquid-liquid phase transition. Furthermore, an accurate wide range EOS is calculated for He, which is of paramount interest for interior structure models of giant planets and brown dwarfs. A high pressure phase diagram of He is derived. Finally, the miscibility gap of H and He is calculated and its implication for the structure and evolution of giant planets is discussed. %L UG 3800 %9 theses %9 Text %9 Hochschulschrift %U http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2012-0121-8 %U http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2012-0121-8&pdf %U http://nbn-resolving.de/urn:nbn:de:gbv:28-diss2012-0121-8
