By means of first-principles calculation, we study non-trivial electronic properties of correlated/topological materials. We also aim at predicting intriguing phenomena originating from many-body correlations and designing novel functional materials/systems. The long-term goal of our research is to establish new guiding principles for materials design. We are also interested in the development of new methods for electronic structure calculation.
Our recent research projects include
- Development of ab initio downfolding methods
- Development of density functional theory for superconductors
- Superconductivity in iron-based superconductors, cuprates,
  doped band insulators, carbon-based superconductors
- Interplay between the spin-orbit coupling and electron correlations in 5d
  electron systems
- Exotic electronic structure of giant Rashba systems, topological insulators
- Giant thermopower in transition-metal compounds
- Multi-pole physics in heavy fermion compounds
