| Research Abstract |
Liquid is one of the three most fundamental states of matter, its basic understanding is far behind that of gas and solid states. We have studied unsolved important problems of liquids, such as liquid-liquid transition, glass transition, crystallization, water's anomalies, and nonlinear flow behavior. We have revealed that the spatio-temporal hierarchy of liquids plays a crucial role in all these phenomena. We have shown that they cannot be understood on the basis of the conventional picture of the liquid state, in which a liquid is regarded as random and isotropic at any length scale. This indicates that we need to reconstruct a liquid-state theory at the fundamental level, taking the spatio-temporal hierarchy into account.
