  2. 1. Strong n-generators in some one-dimensional domains

    Author : Kerstin Pettersson; Daniel D Anderson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Abstract : Let R be a commutative Noetherian one-dimensional domain such that each ideal in R can be generated by n elements. A strong n-generator in R is an element r which can be chosen as one of n generators for each ideal in which it is contained. READ MORE

  4. 2. Theoretical studies on one-, two- and three-dimensional carbon structures

    Author : Mattias Hjort; Linköpings universitet; []
    Keywords : Tight binding; Hückel; Fullerenes; graphite; Anderson localization; transfer matrix;

    Abstract : This thesis deals with electronic structure calculations in large carbon based materials, Especially graphite like structures have been studied. For this the tight binding method together with more sophisticated quantum chemical methods has been utilised. READ MORE

  5. 3. Interaction and disorder in helical conductors

    Author : Anders Ström; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; physics; helical conductors; topological insulators; Anderson localization; condensed matter;

    Abstract : Different effects from electron-electron interactions and disorder in helical and quasi-helical conductors are studied using bosonisation and renormalisation group methods. The combined effects of Rashba spin-orbit interaction and magnetic Kondo-type impurities in the helical edge liquids of quantum spin Hall insulators, are investigated. READ MORE

  6. 4. Electronic properties of double quantum wires in a magnetic field

    Author : Sviatoslav Korepov; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Abstract : The electronic properties of double quantum wires (DQW) in presence of a per-pendicular magnetic field are investigated theoretically. Analytical solution of theproblem of electronic spectrum is obtained in the framework of the two-subbandmodel for the DQW. READ MORE

  7. 5. Electron transport in π-conjugated systems

    Author : Magnus Paulsson; Libero Zuppiroli; Linköpings universitet; []
    Keywords : ;

    Abstract : This thesis deals with theoretical studies of electron localization and conductance in conjugated molecular systems. Anderson localization of electrons is examined for nearly one-dimensional systems. This work was performed to understand the peculiar electronic properties of conducting polymers. READ MORE
