   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. Electromagnetic Duality in SO(3) Yang-Mills Theory : Bachelor Thesis

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Jim Lundin; [2018]
   Keywords : Montonen-Olive conjecture; BPS states; t Hooft-Polyakov monopole; Witten effect; SL 2; Z invariance;

   Abstract : We introduce the historical context and motivation for the search for magnetic monopoles or monopole-like objects. Beginning the theoretical part we investigate the properties of groups as they relate to symmetries in physical theories. READ MORE
