  2. 1. Investigating Hydrogenous Behavior of Zintl Phases : Interstitial Hydrides, Polyanionic Hydrides, Complex Hydrides, Oxidative Decomposition

    Author : Verina Kranak; Ulrich Häussermann; Gordon Miller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zintl phases; Hydrogenous Zintl phases; Polyanionic Zintl phases; Interstitial Zintl phases; Inorganic Chemistry; oorganisk kemi;

    Abstract : This thesis is an investigation into the hydrogenous behavior of Zintl phases. Zintl phases are comprised of an active metal (i.e alkali, alkaline earth, and rare earth) and a p-block element. The discussion gives an overview of the influence hydrogen affects the electronic and geometric structure of Zintl phases and subsequent properties. READ MORE

  4. 2. Geometric and Topological Phases with Applications to Quantum Computation

    Author : Marie Ericsson; Ignacio Cirac; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; geometric phases; topological phases; quantum computation; mixed states; completely positive maps; Fysik; Physics; Fysik; fysik; Physics;

    Abstract : Quantum phenomena related to geometric and topological phases are investigated. The first results presented are theoretical extensions of these phases and related effects. Also experimental proposals to measure some of the described effects are outlined. READ MORE
