  1. 1. Spin splitting in open quantum dots and related systems

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

    Sammanfattning : 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. LÄS MER

    Sammanfattning : This thesis focuses on how middle school children organize peer group relationships through various forms of so-called relational talk (Evaldsson, 2007), while they also negotiate and more generally make sense of friendships and romantic relationships. Prior micro-sociological research has demonstrated how children in everyday language practices through, for example, teasing, assessments, and storytelling—articulate and manage social relationships and behaviors, moral views, and shared cultural knowledge, thereby constructing their emerging social worlds (see Goodwin & Kyratzis, 2011, for an overview).
