   Sammanfattning : Defects in quantum field theories appear in many different contexts and are of great physical interest. Among other things, defects are used to describe the Kondō effect in condensed matter, confinement in quantum chromodynamics, Rényi entropy in quantum information and cosmic strings in string theory.

   Sammanfattning : In this licentiate thesis, we provide the context and background for our work One-loop algebras and fixed flow trajectories in adjoint multi-scalar gauge theory (published in JHEP) on the renormalization group flow for a multi-scalar SU(N) gauge theory. The background consists of a description of renormalization group flow, with a focus on beta functions andhow to find fixed points, and multi-scalar theories. LÄS MER
