| Outline of Final Research Achievements |
Magnetic degrees of freedom have played a main role in our modern technology for many years. Recently, there appeared a considerable interest on non-magnetic degrees of freedom inherent in the nature of electrons. In this study, we have discussed various properties arising from such nonmagnetic degrees of freedom: "Chirality" formed by several spins turns out to be a main player in Kondo problem in tetrahedron spin configuration. "Quadrupole" moments that is anisotropic charge distributions of electrons, give a new opportunity of critical phenomena related to so called XY universality class. We have also developed a new Monte Carlo algorithm for one-dimensional systems and a theory for certain class of superconductivity. We expect that these results becomes the fundamentals for future studies in this field.
