Emergent Functionality Design Research Unit

Our unit theoretically investigates emergent functionalities in quantum materials, such as electrical conductivity and magnetism. We use numerical and analytical calculations to explore the rich functional phenomena in strongly correlated electron systems where various degrees of freedom interact, such as charge, spin, orbital, and sublattice. Specifically, we calculate the electrical and optical conductivity by linear and nonlinear response theory, numerically simulate thermal equilibrium states and non-equilibrium dynamics, and design new materials based on first-principles calculations for spin-charge coupled systems, topological magnetic textures, and topological electronic states.
