Spin textures in k space
We study nontrivial spin textures in Bismuth thin film, ferroelectric oxides bulk and film, topological insulators, and the system of Dirac electrons.
Magnetism in Graphene
We predict the graphene nano ribbon have carrier-induced non-collinear magnetism (weak ferromagnetism).
Nature Physics Research Highlight
Berry's Phase
We have developed computational code to evaluate Berry’s phase of insulating materials. The macroscopic electric polarization is equivalent to the Berry’s phase. The Berry's curvatures gives anomalous velocity for electrons and it resulted anomalous Hall conductivity.
