Outline of Final Research Achievements

I have discussed various systems in field theory and condensed matter theory. As for field theory, I have discussed supersymmetric theories, field theories on compactified space, (baby-)Skyrme models and so on. As for condensed matter systems, I have discussed Bose-Einsten condensate of ultracold atomic gases, superconductors, helium superfluids, magnets and so on. I have lso delt with high density quark matter, high density nuclear matter and neutron stars.
