1. On string integrability A journey through the twodimensional 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. Ways of determining and characterising resonances in scattering processes
University dissertation from Stockholm : Department of Physics, Stockholm UniversityAbstract : Scattering cross sections very often display structures. To clarify if these structures correspond to resonances one has to check if they are poles of the scattering matrix (Smatrix) in the fourth quadrant of the complex momentum plane. Furthermore, the states corresponding to these poles also need to have an appropriate scattering amplitude. READ MORE

3. Waves and rays in open billiards
University dissertation from Linköping : Linköpings universitetAbstract : Semiconductor systems where the deBroglie wavelength of the electron is comparable to the size of the system are called mesoscopic. Such systems are readily produced in laboratories, and have been studied extensively. These systems offer possibilities to study the borderline between quantum and classical physics, chaos and more.
