Outline of Final Research Achievements

Statistical mechanics plays an important role to study a system consisting of many particles. However, a system having gravity or Coulomb force, which reach to a long distance, breaks a basic assumption of statistical mechanics, and expresses anomalous phenomena from the view point of statistical mechanics. This research project has obtained results on such anomalous phenomena and their universality. Furthermore, obtained results are applied to synchronization phenomenon, for instance.

Academic Significance and Societal Importance of the Research Achievements

自然界には4つの力があり、そのうちの二つである重力とクーロン力は力が遠くまで及ぶ。これらの力については、天体物理学やプラズマ物理学などで個別に長く研究されて来たが、その力学特性と普遍性に関する研究は最近30年程で発展してきた新しい分野である。その重要性に反し、日本においては研究者数も多くなく、本研究で得られた成果は当該分野における日本の貢献を世界に示すために重要な役割を果たしている。
