Judit Romhanyi is a theoretical physicist working in the field of condensed matter and materials research. Her group studies materials in which the strong interactions lead to fascinating emergent quantum phenomena. They seek to understand and characterize quantum materials by developing microscopic models describing them. They focus on experimentally motivated problems and are especially interested in compounds where the interplay of charge, spin, orbital, and lattice degrees of freedom is vital, leading to exotic physical properties of quantum origins. Exploring these systems is not only exciting but also has potentials in technological applications. Their interests include frustrated magnetism, spin-orbital physics, multiferroic materials, and topological phases of matter.
