Research summary

My research focuses on the theoretical description of strongly correlated electron systems. Examples of such materials include systems with partially filled d- or f-shells, such as transition metal oxides, where the Coulomb repulsion between electrons plays a crucial role due to the narrowness of these orbitals. I am particularly interested in interaction-driven transitions between metallic and insulating states, magnetism, unconventional superconductivity, and transport phenomena. To study these effects theoretically, I employ modern quantum field theoretical methods in combination with numerical simulations. The goal of this research is to achieve a deeper understanding of complex material properties and, ultimately, to design novel compounds with desired functionalities.
