To understand correlated quantum materials, we develop new theoretical concepts, advanced methods and better algorithms. For our recent efforts, see:

Since 2002, we have participated in the development of the DFT software package 'OpenMX (Open source package for Materials eXplore)'. This pseudopotential local-basis code has been developed through international collaboration, under the main supervision of Prof. Ozaki at ISSP, University of Tokyo. Our main interests and contributions lie in methods for correlated electronic structure and magnetism. 

The Jx code performs magnetic force calculations using DFT solutions as input. It supports both collinear and noncollinear spin Hamiltonian. For the former, implementation details can be found in
