11. Development and application of Muffin-Tin Orbital based Green’s function techniques to systems with magnetic and chemical disorder
Abstract : Accurate electronic structure calculations are becoming more and more important because of the increasing need for information about systems which are hard to perform experiments on. Databases compiled from theoretical results are also being used more than ever for applications, and the reliability of the theoretical methods are of utmost importance. READ MORE

12. Theoretical understanding of stability of alloys for hard-coating applications and design
Abstract : The performance of modern hard coating materials puts high demands on properties such as hardness, thermal stability and oxidation resistance. These properties not only depend on the chemical composition, but also on the structure of the material on a nanoscale. READ MORE

13. Theoretical prediction of properties of atomistic systems : Density functional theory and machine learning
Abstract : The prediction of ground state properties of atomistic systems is of vital importance in technological advances as well as in the physical sciences. Fundamentally, these predictions are based on a quantum-mechanical description of many-electron systems. READ MORE

14. Thermal Expansion and Local Environment Effects in Ferromagnetic Iron-Based Alloys : A Theoretical Study
Abstract : The Nobel Prize for Physics 1920 was awarded to C.-E. Guillaume for his discovery of properties of nickel steels. He had previously observed that certain iron-nickel alloys exhibit the Invar effect i. READ MORE

15. Theoretical Considerations of Local Environment Effects in Alloys
Abstract : This thesis is devoted to a theoretical study of local environment effects in alloys. A fundamental property of a disordered system is that all chemically equivalent atoms are different due to their different chemical environments, in contrast to an ideal periodic solid where all the atoms that occupy equivalent positions in the crystal have exactly the same physical properties.
