    Abstract : This work presents new development and applications of ab-initio simulation tools for material science. Focus lies on materials with strong electronic correlation and strong spin-orbit coupling. READ MORE

  4. 2. Ionization Influence on the Dynamics of Simple Organic Molecules

    Author : Tomoko Akiyama; Carl Caleman; Oscar Grånäs; Olle Björneholm; Maria Hahlin; Uppsala universitet; []
    Keywords : Small organic molecule; Density functional theory; bond integrity; Symmetric structure;

    Abstract : This licentiate thesis is devoted to the investigation of how bonding in simple organic molecules are affected by X-ray beam irradiation. The investigation targets molecules with three carbons as their main-chain structure. The stability of the bonds under ionization are simulated using the SIESTA package. READ MORE
