1. Lattice dynamics : From fundamental research to practical applications
Sammanfattning : The reason to perform calculations in material science usually falls into one of two categories: to predict or explain the origin of material properties. This thesis covers first-principle calculations for solids at extreme conditions, from both of the two mentioned categories. LÄS MER
2. Lattice dynamics in perovskites for green energy applications: A theoretical perspective
Sammanfattning : Electrolyzers and fuel cells are used in green energy applications, electrolyzers split water to produce hydrogen, which can then be used in fuel cells to produce energy. Oxide perovskites have shown favorable properties for applications in this area, e.g., as electrolyte and cathode material in fuel cells and electrolyzers. LÄS MER
3. Electronic Structure and Lattice Dynamics of Elements and Compounds
Sammanfattning : The elastic constants of Mg(1-x)AlxB2 have been calculated in the regime 0.... LÄS MER
4. Development and application of techniques for predicting and analysing phonon-derived materials properties
Sammanfattning : The thermodynamic properties of materials are of great interest for both scientists and engineers. A large contribution to many properties stems from the vibrational motion of the atoms in the material. An understanding of the dynamics of the vibrating atoms is therefore important for many other areas as well, including, e.g. LÄS MER
5. Meson Properties in Partially Quenched Effective Field Theory
Sammanfattning : 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. LÄS MER
