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

   University essay from KTH/Fysik

   Author : Yashar Honarmandi; [2022]
   Keywords : 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;

   Abstract : 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. 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
