  1. 1. Topological properties of flat bands in generalized Kagome lattice materials

    University essay from KTH/Fysik

    Author : Daniela Pinto Dias; [2021]
    Keywords : tight-binding; topological insulators; flat bands; edge states; honeycomb-Kagome lattice; tätt bindande modell; topologiska isolatorer; platta band; kanttillstånder; bikakan-Kagome gitter;

    Abstract : Topological insulators are electronic materials that behave like an ordinary insulator in their bulk but have robust conducting states on their edge. Besides, in some materials the band structure presents completely flat bands, a special feature leading to strong interactions effects. READ MORE

  3. 2. From the quantum Hall effect to topological insulators : A theoretical overview of recent fundamental developments in condensed matter physics

    University essay from Teoretisk fysik

    Author : Hjalmar Eriksson; [2010]
    Keywords : quantum Hall effect; topological insulator; topological insulators; Hall effect; quantum spin Hall effect; kvantiserade Halleffekten; topologisk isolator; topologiska isolatorer; Halleffekten; kvantiserade spin-Halleffekten;

    Abstract : In this overview I describe the simplest models for the quantum Hall and quantum spin Hall effects, and give some general indications as to the description of topological insulators. As a background to the theoretical models I will first trace the development leading up to the description of topological insulators . READ MORE
