Outline of Final Research Achievements

Phase transition phenomena in equilibrium environments are well understood, but phase transition phenomena in non-equilibrium environments, where energy and material flows exist, are not well understood. In order to investigate phase transition phenomena in non-equilibrium environments, I constructed several continuum equations for active materials, such as cellular tissues and self-propelled particles, and developed the method of renormalization group, which is useful for defining universality classes of phase transition.
