Theses
Heavy Quark QCD at Finite Temperature and Density Using an Effective Theory
Supervisor(s): Prof. Dr. Owe Philipsen, and Prof. Dr. Dirk-Hermann Rischke
In this work I used an effective theory approach to study the cold and dense limit of heavy QCD from first principles. I developed both computational and graphical tools and methods for carrying out the necessary mathematics to high order. Much of the work is also dedicated to the methods of resummation and their advantages.
The Chiral Phase Transition in QCD: Mean-Field Versus the Functional Renormalisation Group
Supervisor(s): Prof. Jens Oluf Andersen
For my masters work I made use of low energy effective theories, more specifically the quark extended linear sigma model, to analyse the properties of the breaking of chiral symmetry in QCD, and the emerging phase diagram. Also made use of the functional renormalisation group to extract the correct low energy properties of the quantum field theory.
