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.

液体是物质最基本状态之一，其基本理解远远落后于天然气和固态。我们研究了液体的未解决的重要问题，例如液液过渡，玻璃过渡，结晶，水的异常和非线性流动行为。我们透露，液体的时空层次结构在所有这些现象中起着至关重要的作用。我们已经表明，无法根据液态的常规图片对它们进行理解，在这种情况下，液态在任何长度尺度上被视为随机和各向同性。这表明我们需要考虑到时空层次结构，在基本层面上重建液态理论。
