16. Density Functional Theory Applied to Materials for Spintronics
Abstract : The properties of dilute magnetic semiconductors have been studied by combined ab initio, Monte Carlo, and experimental techniques. This class of materials could be very important for future spintronic devices, that offer enriched functionality by making use of both the spin and the charge of the electrons. READ MORE

17. Macroeconomic Studies on Fiscal Policy and Real Exchange Rates
Abstract : This thesis contains four empirical macroeconomic studies and the papers may briefly be summarized as follows. In the first paper, we use both descriptive statistics and regression analysis to investigate whether movements in real exchange rates and money supply before and during fiscal contractions matter for the macroeconomic outcome.

18. Van der Waals Interactions in Density Functional Theory
Abstract : Density functional theory is a very important method for calculating ground-state properties for atoms, molecules and solids. Albeit exact in principle, its implementation requires an approximation for the so-called exchange-correlation energy. READ MORE

19. Macroeconometric Studies of Private Consumption, Government Debt and Real Exchange Rates
Abstract : Advances in time series analysis during the last two decades have stimulated research in a number of areas in macroeconomics. This thesis is a compilation of five essays using cointegrated vector autoregressive (VAR) models, unit root tests and regime switching models to investigate the behavior of private consumption, public debt and the real exchange rate.

20. Theory of van der Waals bonding: from bulk materials to biomolecules
Abstract : Sparse matter is abundant in Nature.It encompasses systems characterized by an intrinsic low density of electrons in sizeable regions, where the van der Waals forces contribute considerably to cohesion.Given the length scale of the problem, a prediction of these materials requires appropriate tools within a quantum-mechanical framework.
