1. The Impact of Swampland Conjectures
University essay from Uppsala universitet/Teoretisk fysikAbstract : The Swampland program is way of sorting effective field theories based on conjectures of how an effective field theory consistent with quantum gravity should look like. In this thesis we take a closer look at the No Global Symmetries Conjecture, the Weak Gravity Conjecture, the de Sitter Conjecture and the Trans-Planckian Censorship Conjecture. READ MORE

2. Gravitational Decoherence in Macroscopic Quantum Systems
University essay from Uppsala universitet/Teoretisk fysikAbstract : The problem of how quantum mechanics gives rise to classicality has been debated for more than a century. A commonly proposed solution is decoherence, i.e. the gradual decay of superpositions in open quantum systems due to their inevitable interaction with their environment. READ MORE

3. 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
