1. 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

2. Calibration of the ATLAS calorimeters and discovery potential for massive top quark resonances at the LHC
University dissertation from Stockholm : Department of Physics, Stockholm UniversityAbstract : ATLAS is a multi-purpose detector which has recently started to take data at the LHC at CERN. This thesis describes the tests and calibrations of the central calorimeters of ATLAS and outlines a search for heavy top quark pair resonances. READ MORE

3. Phenomenology of Inert Scalar and Supersymmetric Dark Matter
University dissertation from Stockholm : Department of Physics, Stockholm UniversityAbstract : While the dark matter has so far only revealed itself through the gravitational influence it exerts on its surroundings, there are good reasons to believe it is made up by WIMPs – a hypothetical class of heavy elementary particles not encompassed by the Standard Model of particle physics.The Inert Doublet Model constitutes a simple extension of the Standard Model Higgs sector.

4. 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

5. Numerical Simulations of Plasmonic Nanostructures
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : This thesis focuses on the study of metallic nanostructures that support plasmons. Special emphasis is devoted to two specific numerical methods that allow us to predict plasmon characteristics: the discrete dipole approximation (DDA) and the Green's tensor (GT) method. READ MORE
