1. On string integrability A journey through the two-dimensional hidden symmetries in the AdS/CFT dualities
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : One of the main topics in the modern String Theory are the conjectured string/gauge (AdS/CFT) dualities. Proving such conjectures is extremely difficult since the gauge and string theory perturbative regimes do not overlap. In this perspective, the discovery of infinitely many conserved charges, i.e. READ MORE

2. Development and applications of theoretical algorithms for simulations of materials at extreme conditions
University dissertation from Linköping : Linköping University Electronic PressAbstract : Materials at extreme conditions exhibit properties that differ substantially from ambient conditions. High pressure and high temperature expose anharmonic, non-linear behavior, and can provoke phase transitions among other effects. Experimental setups to study that sort of effects are typically costly and experiments themselves are laborious. READ MORE

3. Theoretical prediction of properties of atomistic systems Density functional theory and machine learning
University dissertation from Linköping : Linköping University Electronic PressAbstract : The prediction of ground state properties of atomistic systems is of vital importance in technological advances as well as in the physical sciences. Fundamentally, these predictions are based on a quantum-mechanical description of many-electron systems. READ MORE

4. Searches for Particle Dark Matter Dark stars, dark galaxies, dark halos and global supersymmetric fits
University dissertation from Stockholm : Department of Physics, Stockholm UniversityAbstract : The identity of dark matter is one of the key outstanding problems in both particle and astrophysics. In this thesis, I describe a number of complementary searches for particle dark matter. READ MORE
