  2. 16. Magnetotransport and Persistent Currents in Ballistic Microstructures

    Author : Thomas Swahn; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this Thesis we discuss properties of different ballistic microstructures in the presence of a magnetic field. Three topics have been studied: (i) the magnetoconductance of a three-dimensional (3D) microwire, (ii) magnetotransport and persistent currents in a two-dimensional so called "quantum dot" in a gated AlGaAs heterostructure, and (iii) some magnetotransport properties of a quasi one-dimensional conducting channel in the same kind of material.

  4. 17. Electron transport, interaction and spin in graphene and graphene nanoribbons

    Author : Artsem Shylau; Igor Zozoulenko; Stephan Roche; Linköpings universitet; []
    Keywords : ;

    Abstract : Since the isolation of graphene in 2004, this novel material has become the major object of modern condensed matter physics. Despite of enormous research activity in this field, there are still a number of fundamental phenomena that remain unexplained and challenge researchers for further investigations. READ MORE

  5. 18. Trends in Magnetism : From Strong Correlations to “-onics” Technology

    Author : Dmitry Yudin; Olle Eriksson; Grigori Volovik; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Strongly interacting electron systems; Spin dynamics; Topological matter; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Despite of enormous progress in experimental nanophysics theoretical studies of low-dimensional electron systems still remains a challenging task. Indeed, most of the structures are strongly correlated, so that an effective perturbative treatment is impossible due to the lack of a small parameter. READ MORE

  6. 19. Electronic Properties of Nanotubes

    Author : Alex Kleiner; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis deals with various aspects of the electronic properties of carbon nanotubes and of generic nanotubes in magnetic fields. Carbon nanotubes are highly symmetric objects on the nanometer scale which show an interesting interplay of their geometry with electronic properties. READ MORE

  7. 20. Non-local behaviour from local interactions

    Author : Thomas Kvorning; Thors Hans Hansson; Ady Stern; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : With the discovery of the quantum Hall effect more than thirty years ago, a whole new field emerged—that of topological quantum matter. This field is now a very mature one, and many different aspects are covered in the literature. READ MORE
