RIKEN Center for Emergent Matter Science Strong Correlation Theory Research Group
Group Director: Naoto Nagaosa (D.Sc.)
Research Summary

We study theoretically the strongly correlated electronic states in solids from the viewpoint of topology and explore new functions, including non-dissipative currents. Combining first-principles electronic structure calculations, analytic methods of quantum field theory and numerical analysis of models for correlated systems, we predict and design magnetic, optical, transport and thermal properties of correlated electrons focusing on their internal degrees of freedom such as spin and orbital. In particular, we study extensively the nontrivial interplay between these various properties, i.e., cross-correlation, and develop new concepts such as electron fractionalization and non-dissipative quantum operation by considering the topology given by the relativistic spin-orbit interaction and/or spin textures.
