1. Model building on gCICYs
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : Prompted by the success of heterotic line bundle model building on Complete Intersection Calabi Yau (CICY) manifolds and the new developments regarding a generalization thereof, I analyze the possibility of model building on generalized CICY (gCICY) manifolds. Ultimately this is realized on two examples of gCICYs, one of which topologically equivalent to a CICY and one inequivalent to any previously studied examples. READ MORE

2. Finiteness of Complete Intersection Calabi Yau Threefolds
University essay from Uppsala universitet/Teoretisk fysikAbstract : Of many modern constructions in geometry Calabi Yau manifolds hold special relevance in theoretical physics. These manifolds naturally arise from the study of compactification of certain string theories. READ MORE

3. Browsing the Web of Amplitudes
University essay from Uppsala universitet/Teoretisk fysikAbstract : We begin by studying field-theory amplitude relations such as the Kleiss-Kuijf, Bern-Carrasco-Johansson, Kawai-Lewellen-Tye and the double copy construction, which are important ingredients in this thesis. Going beyond the field-theory limit we study how the gauge-sector of the heterotic string relates to type I amplitudes through the single valued projection of multiple zeta values. READ MORE
