| Outline of Final Research Achievements |
While vortexes are ubiquitous in the Universe, the basic mechanism of their creation remains incompletely understood. The delineation of the self-organizing processes will bring about immense advances in physics and engineering of various vertical phenomena, leading to innovations in controlling or optimizing vertical structures.
The plasma vortex in a magnetospheric system has been studied in the perspective of space-time geometry. In a magnetosphere, the plasma self-organizes to a state with a steep density gradient. Although the creation of gradient is seemingly contradicting the entropy principle, the resulting nontrivial structure is a stable equilibrium if we properly take into account the topological constraint. We have given the experimental proof of the spontaneous confinement of plasma in a dipole magnetic field. Because of the high-performance plasma confinement and heating, this system has scientific potential for realizing advanced fusion.
