| Outline of Final Research Achievements |
Topological semimetals have recently attracted considerable theoretical and experimental interest since they exhibit anomalous electromagnetic response and topological superconductivity.
The first research outcome is to establish the general theory of crossing-line-node semimetals and propose candidate materials. This research may stimulate experimental search for topological materials.
The second research outcome is to clarify topological superconductivity in antiperovskite type Dirac semimetals and investigate a new topological phase with a higher winding number.
