Understanding and exploiting the properties of materials are essential goals in condensed matter physics and materials science. In this regard, first-principles quantum-mechanical calculations based on density functional theory (DFT) have emerged as one of the most important components of the theorist’s toolbox, as they have successfully revealed material properties at feasible computational costs. My research focuses on solid-state materials containing d- or f-orbital electrons, with the aim of investigating their microscopic electronic and magnetic properties using DFT calculations and low-energy effective model analysis. In particular, I am interested in the responses of these systems to various external or internal perturbations, such as pressure, magnetic fields, doping, and defects. To properly account for many-body effects arising from spatially localized d or f shells, dynamical mean-field theory combined with DFT will also be incorporated.
