    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; Density fitting; CASSCF; Analytical gradients; Photochemistry; X-ray spectroscopy; Kemi med inriktning mot kvantkemi; Chemistry with specialization in Quantum Chemistry;

    Abstract : Multiconfigurational quantum chemistry methods, and especially the multiconfigurational self-consistent field (MCSCF) and multireference perturbation theory (MRPT2), are powerful tools, particularly suited to the accurate modeling of photochemical processes and transition metal catalysis. However, they are limited by their high computational cost compared to other methods, especially density functional theory. READ MORE

  4. 2. MATTER-ANTIMATTER INTERACTIONS : The hydrogen-antihydrogen system and antiproton-matter interactions

    Author : Henrik Stegeby; Roland Lindh; Dage Sundholm; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antimatter; antiproton; matter-antimatter interactions; hydrogen-antihydrogen system; Kemi med inriktning mot kvantkemi; Chemistry with specialization in Quantum Chemistry;

    Abstract : Ever since antiparticles were discovered their nature has been something of a mystery. They were postulated to be identical to regular particles except for having opposite charge, but this would imply that an equal amount of antiparticles and particles should have been created at the beginning of time.
