Outline of Final Research Achievements |
There are two highlights in the results of this research project. The first is to succeed in completing a basic theory for dynamical brane-world scenario by topological solitons which is more natural than many previous brane-world models. Especially, we resolved a longstanding problem of localizing non-Abelian gauge fields on topological solitons. Secondly, we revealed dynamics of half quantized vortices in multi-component Bose-Einstein condensations of ultra-cold atomic gases, and applied it to the quantum chromodynamics (QCD) and got a new insight for a longstanding problem of QCD, namely color confinement. The main purpose of this research project is discovering new and universal methods which cover particle physics, nuclear physics, cosmology, and condensed matter physics. To this end, we focused on symmetry, spontaneous symmetry breaking, and topological solitons in all the studies. The results mentioned above really embody that purpose and open up a new research method in physics.
