Outline of Final Research Achievements

(1) We have addressed the problem of two-dimensional 3He system having a liquid phase. In this study, we found that the spin triplet state forms a metastable liquid phase by obtaining the relationship between energy and particle number density by using the variational method using energy functional. (2) As to the few-body systems of quarks, it was clarified how much the confinement properties are retained by Abelian part and monopole part of QCD vacuum. (3) We studied viscoelastic body as a new development of classical system. Based on the experience of the lattice gauge theory in the research of (2) above, it succeeded in elucidating the mechanism of velocity jump on the crack growth of viscoelastic body.
