  1. 1. Consequences of a non-trivial band-structure topology in solids : Investigations of topological surface and interface states

    Författare :Magnus H. Berntsen; Oscar Tjernberg; Philip Hofmann; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; spin- and angle-resolved photoelectron spectroscopy; time-of-flight analyzer; laser based light source; topological insulator; topological crystalline insulator; thin films; surface state; interface state; Bi2Se3; Pb1-xSnxSe;

    Sammanfattning : The development and characterization of experimental setups for angle-resolved photoelectron spectroscopy (ARPES) and spin- and angle-resolved photoelectron spectroscopy (SARPES) is described. Subsequently, the two techniques are applied to studies of the electronic band structure in topologically non-trivial materials. LÄS MER

  3. 2. Numerical solutions to non-linear inhomogeneous problems in Superconductivity : From sphalerons to multi-band boundary states and spontaneous magnetic fields

    Författare :Andrea Ludovico Benfenati; Egor Babaev; Sedrakyan Tigran; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Teoretisk fysik; Theoretical Physics;

    Sammanfattning : This thesis is a compilation of theoretical works focused on simulating and studying open questions regarding single and multiband superconductivity. In the last decades, with the discovery of multiband superconductors, the spectrum of potential applications has greatly widened.
