6. Gaps, Traps and Lattices - Correlations in Small Quantum Systems
Abstract : This dissertation investigates properties of two-dimensional many-body systems. Studies are performed using the Spin-Density Functional Theory with the Local Spin-Density Approximation, and numerical exact diagonalization. READ MORE

8. Aspects of the Duality between Supersymmetric Yang-Mills Theory and String Theory
Abstract : This thesis deals with three topics related to the Ads/CFT correspondence. In Paper I, solutions describing the geometry of fractional D1-branes of Type IIB string theory are presented. The running coupling constant is computed on the gauge theory side. READ MORE

9. Meson Properties in Partially Quenched Effective Field Theory
Abstract : Mass corrections and decay constants for light mesons have been calculated in Partially Quenched Chiral Perturbation Theory. The calculations of the charged meson masses have been performed to third order, first for degenerate quark masses, and then, in a second project, for the general case. READ MORE

10. Pion and Kaon Dynamics at Higher Orders in Chiral Perturbation Theory
Abstract : Higher orders calculations of processes involving the pion and kaon pseudo-scalar mesons are presented in the framework of three flavour Chiral Perturbation Theory. The purpose is two-fold. First determining the low energy constants of ChPT that are necessary for higher accuracy predictions. READ MORE
