  1. 6. Global stability analysis of three-dimensional boundary layer flows

    Författare :Mattias Brynjell-Rahkola; Dan Henningson; Philipp Schlatter; Ardeshir Hanifi; Spencer Sherwin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrodynamic stability; transition to turbulence; global analysis; boundary layers; roughness; laminar flow control; Stokes Laplace preconditioner; optimal forcing; crossflow vortices; Ginzburg-Landau; Falkner-Skan-Cooke; Blasius; lid-driven cavity;

    Sammanfattning : This thesis considers the stability and transition of incompressible boundary layers. In particular, the Falkner–Skan–Cooke boundary layer subject to a cylindrical surface roughness, and the Blasius boundary layer with applied localized suction are investigated. LÄS MER

  3. 7. Superconductivity in the presence of magnetic steps

    Författare :Wafaa Assaad; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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

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

    Författare :Jonatan Wårdh; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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
