Akira Takada:

After graduating from Tokyo University at which I studied applied mathematics, I joined Asahi Glass Company. I have been performing a variety of computer simulations of macroscopic and microscopic phenomena on glass. My recent major concern is to construct a bridge between microscopic (glass structure) and microscopic phenomena (glass properties) on glass. I am joining the activities of TC-3 (Glass Structure) and TC-27 (Atomistic modelling and Simulation) under ICG.

In addition, I have a research project at University College London as a visiting professor.

I served as a president at the Japan Society of Industrial and Applied Mathematics (JSAM; a number of member is about 1,700) in 2013-2015. I am a member of Science Council of Japan. I am Fellow of JSIAM and Fellow of SGT (Society of Glass Technology).


Extension of thermodynamic concept using spatial sampling
Akira Takada1*, Pascal Richet2 and Reinhard Conradt3


The thermodynamics of glasses is very important to understand the phenomena of relaxation, glass transition and viscous flow. However, the non-equilibrium states limit the applicability of conventional thermodynamics theory. One of several approaches to extend the conventional theory is to employ the authors' concept named "spatial sampling". The approach uses neither the concept of ensemble nor that of kinetic profiles. The merits and demerits of this concept over the other methods are discussed in the cases of relaxation and glass transition. Several unsolved problems related to statistical thermodynamics are also discussed.
