1. 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

2. Single-Electron Tunneling Spectroscopy in Magnetic Nanoparticles and Molecular Magnets
Abstract : This thesis deals with single-electron tunneling in transistor-like devices in which the central electrode is either a metal nanoparticle (possibly ferromagnetic) or a molecular magnet. The investigated systems split into two different categories, depending on the size of the central island. READ MORE

3. Ab initio prediction of the mechanical properties of alloys
Abstract : At the time of the 50th anniversary of the Kohn-Sham method, ab initio calculations based on density functional theory have formed an accurate, efficient, and reliable method to work on the properties of engineering materials. In this thesis, we use the exact muffin-tin orbitals method combined with the coherent-potential approximation to study the mechanical properties of high-technology materials. READ MORE

4. Ab Initio Investigation of Interfacial and Grain Boundary Properties of Metals and Alloys
Abstract : Phase interface (IF) and grain boundary (GB) are both common yet critical planar defects influencing the mechanical and physical properties of polycrystalline materials. Due to the complex nature of IFs and GBs in terms of structure and chemistry, determining the accurate excess energies associated with these defects is challenging for both experimental measurements and theoretical simulations.

5. Influence of stresses and impurities on thermodynamic and elastic properties of metals and alloys from ab initio theory
Abstract : Stresses and impurities may influence elastic properties, phase stability and magnetic behavior of metals and their alloys. A physical understanding of this influence is of great importance to both fundamental science and technological applications. READ MORE
