  3. 23. Distorted Space and Multipoles in Electronic Structure Calculations

    Author : Fredrik Bultmark; Lars Nordström; Susanne Mirbt; Olle Eriksson; Sergej Savrasov; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; materials science; condensed matter theory; density functional theory; Magnetism; Atomic and molecular physics; Atom- och molekylfysik;

    Abstract : This thesis concerns methods for electronic structure calculations and some applications of the methods. The augmented planewave (APW) basis set and it’s relatives LAPW (linearised APW) and APW+lo (local orbitals) have been widely used for electronic structure calculations. READ MORE

  4. 24. Quantum transport in photoswitching molecules : An investigation based on ab initio calculations and Non Equilibrium Green Function theory

    Author : Anders Odell; Anna Delin; Anders Niklasson; Jonas Fransson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular electronics; electron transport; electron structure; density functional theory; non equilibrium green function theory; Electronic structure; Elektronstruktur;

    Abstract : Molecular electronics is envisioned as a possible next step in device miniaturization. It is usually taken to mean the design and manufacturing of electronic devices and applications where organic molecules work as the fundamental functioning unit. READ MORE

  5. 25. Electronic Structure and Core-Hole Dynamics of Ozone : Synchrotron-radiation based studies and ab-initio calculations

    Author : Karoline Wiesner; Svante Svensson; Olle Björneholm; Robert E. Continetti; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik;

    Abstract : The electronic structure of the ozone molecule O3 has been studied with spectroscopy techniques and computations. The investigation was focused on O3 in a core-hole state. The electronic configuration and the nuclear dynamics have been found to be highly correlated. READ MORE
