| Outline of Final Research Achievements |
We have theoretically investigated novel superfluid states in Fermion and Boson systems. As for the fermions, we study superconducting states under applied magnetic fields and identify the pairing functions for the three heavy fermion materials: CeCu2Si2, UPt3 and UBe13 in collaboration with experimental groups. We have succeeded in determining the pairing symmetries for each material and new identification of full gapped multi bands for CeCu2Si2.
As for the bosons, we find the stable skyrmion states by introducing an artificial guage potential.
