  1. 1. Theory of electron transport in superconducting heterostructures

    Författare :Magnus Hurd; Chalmers University of Technology; []
    Nyckelord :high-Tc; superconducting junctions; transport processes; heterostructures; BCS theory; Ginzburg-Landau theory; superconductors; Josephson effect; critical currents; grain boundaries; superconductivity;

    Sammanfattning : .... LÄS MER

  2. 2. Multicomponent superconductivity : Vortex matter and phase transitions

    Författare :Johan Carlström; Egor Babaev; Leo Radzihovsky; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Superconductivity; Ginzburg Landau; field theory; Iron pnictide;

    Sammanfattning : The topic of this thesis is vortex-physics in multi component Ginzburg- Landau models. These models describe a newly discovered class of super- conductors with multiple superconducting gaps, and possess many properties that set them apart from single component models. LÄS MER

  3. 3. Superconductivity in the presence pf magnetic steps

    Författare :Wafaa Assaad; Matematik LTH; []
    Nyckelord :Ginzburg-Landau theory; Schrodinger operators with magnetic fields; Superconductivity; spectral theory; PDE; quantum mechanics;

    Sammanfattning : This thesis investigates the distribution of superconductivity in a Type-II planar, bounded, and smooth superconductor submitted to a piecewise-constant magnetic field with a jump discontinuity along smooth curves---the magnetic edge. This discontinuous case has not been treated before in the mathematics literature, where the considered applied magnetic field is usually assumed to be smooth. LÄS MER

  4. 4. On the Growth of Bone through Stress Driven Diffusion and Bone Generation Processes

    Författare :Gustav Lindberg; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone growth; Osteogenesis; Diffusion in bone; stress enhanced diffusion; Ginzburg-Landau; phase-field; diffusion experiment; Conductivity; Kalman filter; finite element method; Fourier series; Fick’s law; Osteology;

    Sammanfattning : In order to prevent or modify bone degeneration due to rest or due to diseases such as osteopenia and osteoporosis, the modeling and remodeling of bone tissue must be better understood. In this thesis it is assumed that the primary condition leading to bone growth is a change of the chemical environment caused by transport of matter resulting from stress driven diffusion. LÄS MER

  5. 5. Fluctuating superconductivity and pair-density wave order in the cuprate superconductors

    Författare :Jonatan Wårdh; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Cuprates; fluctuating superconductivity; pair-density wave; Ginzburg-Landau theory; vestigial order; nematicity; paraconductivity;

    Sammanfattning : High-temperature superconductors are some of nature’s most enigmatic materials. Besides carrying a supercurrent, these materials manifest a range of electronic and structural orders. LÄS MER
