Research Abstract

We have recently carried out research into liquids by a new experimental method called "fast sound measurement" which is proposed by us. This method can directly detect fluctuations in liquids and it can make crucial contribution to understand the liquid-liquid phase transition phenomena of water.
In this project, we applied this method to (1) water-alcohol mixture and (2) liquid Te system which exhibits similar thermodynamic anomalies to liquid water. We demonstrated the validity of the method through these application and also discussed fluctuations in these systems.
