Hierarchical Self-Organization and Dynamics of Liquids

液体是物质的三种最基本状态之一，对它的基本认识远远落后于对气体和固体状态的认识。我们研究了液体中尚未解决的重要问题，如液-液转变、玻璃化转变、结晶、水的异常和非线性流动行为。我们已经揭示了液体的时空层次在所有这些现象中起着至关重要的作用。我们已经表明，它们不能根据传统的液态图像来理解，在这种图像中，液体被认为是随机的，在任何长度尺度上都是各向同性的。这表明我们需要在基本水平上重建液态理论，考虑到时空层次。

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.
