  1. 1. Physics from Wholeness Dynamical Totality as a Conceptual Foundation for Physical Theories

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Barbara Piechocinska; Uppsala universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; wholeness; elementary embedding; left-distributivity; braids; special braids; entropy; Temperley-Lieb algebra; von Neumann algebra; Potts model; Fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : Motivated by reductionism's current inability to encompass the quantum theory we explore an indivisible and dynamical wholeness as an underlying foundation for physics. After reviewing the role of wholeness in the quantum theory we set a philosophical background aiming at introducing an ontology, based on a dynamical wholeness. LÄS MER

  2. 2. Thermodynamic modelling of composition and crystal structure of ternary nanowires

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Sammanfattning : This thesis describes experimental investigation of thin films made of diluted Pt 1-x Ni x ferromagnet alloy and Nb-Pt 1-x -Nb Josephson junctions. Such Hybrid Superconductor-Ferromagnet (S-F) Structures are of significant interest because of the new physics involved and possible applications in low temperature and spintronic devices. LÄS MER

  4. 4. Transport Studies of Local-Gate Defined Quantum Dots in Nanowires

    Detta är en avhandling från Solid State Physics

    Författare :Carina Fasth; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Semiconductory physics; Fysik; Physics; quantum devices; nanowire; quantum dot; Halvledarfysik;

    Sammanfattning : This thesis focuses on electrical transport in semiconductor InAs nanowires grown by chemical beam epitaxy. Initially, transport length scales of homogeneous InAs n-type nanowires are characterized by low-temperature magnetoconductance measurements. The measurements show phase-coherent conductivity corrections. LÄS MER
