| Outline of Final Research Achievements |
As the primary result of the project, we have demonstrated the new form of electronic orders which involve both conduction and localized f electrons. The composite order appears typically as an itinerant multipole order, or an exotic superconducting order with odd frequency pairing. Secondly, we have shown for the Kondo lattice that the quantum critical point of antiferromagnetism preserves the itinerant nature of heavy electrons. The localized character sets in at another transition within the antiferromagnetic phase. This conclusion is in good agreement with accurate experimental results for some Ce compounds. Thirdly, we have clarified the condition for decrease of the characteristic energy for valence fluctuations by the Coulomb repulsion with conduction electrons. This mechanism is a candidate for emegence of heavy electrons that are insensitive to magnetic fields.
