Research Interests

Our group investigates the emerging phenomena in complex systems based on statistical mechanics. Particularly diverse types of phase transitions, for instance, the explosive percolation and hybrid percolation transitions, and their underlying mechanisms. These researches would be useful for understanding drastic phase transitions in a short time scale, for instance, epidemic spreading. We are also interested in synchronization transitions with metastable states, which should be closely related to the recovery process of consciousness in human brain.
