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. Review of compact spaces for type IIA/IIB theories and generalised fluxes
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : In the present project we study compactifications of type IIA/IIB string theories on toroidal orbifolds. We present the moduli space for N=1 four-dimensional reductions and its topological properties. To fix the value of all moduli, we will construct the most general holomorphic superpotential W using a set of T-dual iterations for the fluxes. READ MORE

3. 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

4. Type IIB compactifications and string dualities
University essay from Uppsala universitet/Teoretisk fysikAbstract : In the present thesis, we offer an introduction to type IIB string compactifications on $\mathbb{T}^{d}/\Gamma$ toroidal orbifolds. We first describe the technical method to construct these spaces and reduce the string background on it. READ MORE

5. AdS/CFT correspondence and c-extremization
University essay from Uppsala universitet/Teoretisk fysikAbstract : In this project we review the method of using c-extremization and computing anomalies to obtain AdS/CFT theories. We start with a quick introduction to CFT's and AdS/CFT correspondence which gives us the tools to later understand the 2D N= (2,0) SCFT and its gravity duals in particular AdS_5xS^5 and AdS_7xS^4 compactified on Riemann surfaces. ..
