  2. 1. Theory of electron transport in superconducting heterostructures

    Author : Magnus Hurd; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-Tc; superconducting junctions; transport processes; heterostructures; BCS theory; Ginzburg-Landau theory; superconductors; Josephson effect; critical currents; grain boundaries; superconductivity;

    Abstract : .... READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Superconductivity in the presence of magnetic steps

    Author : Wafaa Assaad; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ginzburg-Landau theory; Schrodinger operators with magnetic fields; Superconductivity; spectral theory; PDE; quantum mechanics;

    Abstract : 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. READ MORE

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

    Author : Gustav Lindberg; Hållfasthetslära; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Jonatan Wårdh; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cuprates; fluctuating superconductivity; pair-density wave; Ginzburg-Landau theory; vestigial order; nematicity; paraconductivity;

    Abstract : 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. READ MORE
