  1. 1. Higher Forms and Dimensional Hierarchy in Topological Condensed Matter

    Master-uppsats, KTH/Fysik

    Författare :Yashar Honarmandi; [2022]
    Nyckelord :Theoretical physics; topological quantum matter; parametrized systems; Berry phase; higher Berry curvature; effective field theory; topological action; topological insulators; dimensional hierarchy; Teoretisk fysik; topologisk kvantmateria; parametriserade system; Berryfas; högre Berrykrökning; effektiv fältteori; topologisk verkan; topologiska isolatorer; dimensionshierarki;

    Sammanfattning : This report discusses higher differential forms with applications in the study of topological phenomena. The integer quantum Hall effect is first discussed, demonstrating a connection between models on a lattice and quantum field theories bridged by a topological invariant, namely the Chern number.

  3. 2. Axion Electrodynamics and Measurable Effects in Topological Insulators

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Andreas Asker; [2018]
    Nyckelord :Topological Insulators; Axion Electrodynamics; Topological Magnetoelectric Effect; Topological Field Theory; Faraday-Kerr Effect; Topologiska Isolatorer; Axion Elektrodynamik; Topologiska Magnetoelektriska Effekten; Topologisk Fältteori; Faraday-Kerr Effekten;

    Sammanfattning : Topological insulators are materials with their electronic band structure in bulk resembling that of an ordinary insulator, but the surface states are metallic. These surface states are topologically protected, meaning that they are robust against impurities. LÄS MER
