1. 1. Solitons in High Energy Physics

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Edvin Olofsson; [2017]
   Keywords : sine-Gordon model; solitons; high energy physics; particle physics; Thirring model; vortices; magnetic monopoles; homotopy; Physics and Astronomy;

   Abstract : Solitons are solutions to classical field equations that are particle like, meaning they are localized in space, have definite energy and can be stable against deformations into the vacuum. In this thesis we investigate under which circumstances such solutions may exist and what effects their existence could have. READ MORE

3. 2. Equivalence of the sine-Gordon Model and the Massive Thirring Model: Derivations and Application

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Erik Linnér; [2017]
   Keywords : sine-Gordon model; Thirring model; Schwinger model; Bosonization; Physics and Astronomy;

   Abstract : The equivalence of the sine-Gordon model and the massive Thirring model, (1+1) dimensional theories of a single scalar field respectively a single Dirac field, is derived by two alternative approaches. The equivalence is derived by a comparison of the perturbation expansions of the correlation functions of the theories around the corresponding massless theories. READ MORE

4. 3. A summary on Solitons in Quantum field theory

   University essay from Uppsala universitet/Institutionen för teknikvetenskaper

   Author : Hugo Laurell; [2016]
   Keywords : ;

   Abstract : This text is a brief summary on solitons in quantum field theory. An introduction to quantum field theory is made through which certain notions in the theory of solitons in quantum field theory is possible to understand. The explicit time-independent kink solutions are computed for the phi^4- and the sine-Gordon theory. READ MORE
