| Outline of Final Research Achievements |
We have studied the new topological electronic phase in pyrochlore iridates, which is one of the correlated topological semimetals. As a results, we found that a new topological Mott insulating state so called as Weyl Mott insulator can be realized on the verge of band-width controlled Mott transition. Moreover, it turned out that the electrical conductivity of edge state emerging at magnetic domain walls is reduced when the bandwidth is tuned away from Mott transition.
