| Outline of Final Research Achievements |
We developed calculation methods of super processes appearing inevitably at each quantum phase transition. We found several quantum phase transition and quantum many-body effects. By means of the theory of super processes by the multi-reference density functional theory, we derived electronic structure calculation methods with convergence in finite steps. The program determining the magnetic interactions is given, whose algorithm is patented.
Materials dependence of the high-temperature superconductors are verified via the Fermi-surface shape effect, and an enhancement mechanism owing to the buffer layers in cuprate is derived. The hole-doping profile of the multi-layered cuprate is found to be an electron correlation effect. The magnetic super process is evaluated for nano-graphene, where the pseudo-gap Kondo effect is derived. A topological protection effect for the correlated singlet in nano-graphene is derived.
