  2. 1. Quantum transport and spin effects in lateral semiconductor nanostructures and graphene

    Author : Martin Evaldsson; Igor Zozoulenko; Vidar Gudmundsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Electronic transport; Spin related phenomena; Quantum dots; Quantum wires; Two-dimensional electron gas; 2DEG; Graphene; Computational physics; Beräkningsfysik; Physics; Fysik;

    Abstract : This thesis studies electron spin phenomena in lateral semi-conductor quantum dots/anti-dots and electron conductance in graphene nanoribbons by numerical modelling. In paper I we have investigated spin-dependent transport through open quantum dots, i.e., dots strongly coupled to their leads, within the Hubbard model. READ MORE

  4. 2. Spin splitting in open quantum dots and related systems

    Author : Martin Evaldsson; Igor Zozoulenko; Igor Abrikosov; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mesoscopic systems; 2DEG; ballistic transport; quantum dots; spin-polarised transport in quantum dots; spontanueous spin-splitting; Mesoscopic physics; Mesoskopisk fysik;

    Abstract : This thesis addresses electron spin phenomena in semi-conductor quantum dots/anti-dots from a computational perspective. In the first paper (paper I) we have studied spin-dependent transport through open quantum dots, i.e., dots strongly coupled to their leads, within the Hubbard model. READ MORE

  5. 3. Exploring material things in family life : Morality and intimacy in sibling- and child-parent interaction

    Author : Emilia Zotevska; Asta Čekaitė; Ann-Carita Evaldsson; Anna Martín Bylund; Susan Danby; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Family; Children; Materiality; Interaction; Everyday life; Familj; Barn; Materialitet; Interaktion; Vardagsliv;

    Abstract : This study examines the everyday family life of 12 families across Sweden. The study aims to explore the ways in which material things figure in the enactment of everyday family life, that is, how family life is accomplished in interaction between children, parents and material things during everyday activities.
