| Outline of Final Research Achievements |
Several exotic superconductors, including CeCu2Si2, UPd2Al3, (U,Th)Be13 for typical heavy Fermion superconducting materials and highly two-dimensional Sr2RuO4 known for chiral triplet superconductor candidate are investigated theoretically in collaboration with experimental groups. In addition to it, we also studies FeSe among iron pnictide superconductors and SrBi2Se3 for topological material candidates. We have succeeded in identifying possible pairing symmetries realized in some of those materials, which are fully consistent with the experimental data of angle-resolved specific heat measurements done by collaborating experimental groups.
