11. Theoretical studies of Bose-Hubbard and discrete nonlinear Schrödinger models : Localization, vortices, and quantum-classical correspondence
Sammanfattning : This thesis is mainly concerned with theoretical studies of two types of models: quantum mechanical Bose-Hubbard models and (semi-)classical discrete nonlinear Schrödinger (DNLS) models.Bose-Hubbard models have in the last few decades been widely used to describe Bose-Einstein condensates placed in periodic optical potentials, a hot research topic with promising future applications within quantum computations and quantum simulations.

12. Bulk-boundary correspondence in non-Hermitian systems
Sammanfattning : The bulk-boundary correspondence, which in topological insulators describes the relationship between the bulk invariant computed for a system with periodic boundary conditions and the number of boundary states in the corresponding system with open boundary conditions, is well-known and important for predicting the behavior of these systems. In recent years, however, the modeling of dissipative and non-equilibrium systems using non-Hermitian Hamiltonians has become increasingly popular. LÄS MER
13. Solving the correspondence problem in analytical chemistry : Automated methods for alignment and quantification of multiple signals
Sammanfattning : When applying statistical data analysis techniques to analytical chemical data, all variables must have correspondence over the samples dimension in order for the analysis to generate meaningful results. Peak shifts in NMR and chromatography destroys that correspondence and creates data matrices that have to be aligned before analysis. LÄS MER
14. Nominal Morphology in Russian Correspondence 1700-1715 : Part One - Part Two
Sammanfattning : The materials examined here consist of 121 Russian letters dating from 1700-1715. The present study aims to define a stage in linguistic evolution and analyze the morphological heterogeneity in the textual corpus. The letters are divided into three categories: private, semiofficial, and official. LÄS MER
15. Aspects of the Duality between Supersymmetric Yang-Mills Theory and String Theory
Sammanfattning : 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. LÄS MER
