  1. 1. Quasicrystal nanowires in SNS-junctions

    University essay from Uppsala universitet/Materialteori

    Author : Anna Sandberg; [2022]
    Keywords : quasicrystal; Fibonacci quasicrystal; superconductivity; SNS-junction; Josephson junction; proximity effect; Josephson current; Bogoliubov-de Gennes method;

    Abstract : Quasicrystals are systems that are ordered but not periodic. They do however still have long-range order and well-defined diffraction peaks. This leads to interesting properties, like critical states which are neither extended nor localized, and to topological invariants and edge states. READ MORE

  3. 2. Quasicrystals : Classification, diffraction and surface studies

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

    Author : Elisabet Edvardsson; [2015]
    Keywords : quasicrystal; cohomology of groups; reduced lattice; diffraction; X-ray standing waves;

    Abstract : Quasicrystal is the term used for a solid that possesses an essentially discrete diffraction pattern without having translational symmetry. Compared to periodic crystals, this difference in structure gives quasicrystals new properties that make them interesting to study -- both from a mathematical and from a physical point of view.

  5. 4. Quantum Mechanical Conduction of Electrons in 1DFibonacci Quasicrystals

    University essay from KTH/Teoretisk fysik

    Author : Carl-Johan Backman; Johannes Wennberg; [2013]
    Keywords : ;

    Abstract : In this report we model and study the propagation of electrons in one-dimensional (1D) Fibonacci quasicrystals. The quasicrystals are modeled with delta function potentials and created by either arranging their strengths or their spacings as a 2 letter Fibonacci word. READ MORE
