摘要:

1. Materials Informatics Science

Frontiers of Information Science has enabled the massive data handling with reasonable speed,and has made qualitative changes in materials science recently. The simulation handles vastamount of couplings from at most 100 kinds of realistic atoms on the earth with quantummechanical calculations to predict materials properties those are useful for our life. Suchactivities are about to be promoted intensively by several countries as their scientific strategies.The world of quantum mechanics is out of our intuitive expectations and hence the power ofcomputer simulation is essentially in demand. 

2. Quantum many-body theory and Massive Parallel Simulations

We have worked on the statistical simulations involving random number samplings combinedwith quantum many-body theory (Diffusion Monte Carlo method). The framework providesthe most reliable estimation of electronic properties of materials. Our simulations requiremassive computational resources, but inherently in harmony with parallel processing. JAIST'ssuper computing facilities enable us to carry out such simulations. JAIST is a representativecenter of HPC in Japan, possessing four kinds of super computers. 

3. Interdisciplinary Challenge

There is a huge demand for researchers working on physics, chemistry, and materials science,who are good not only at mathematics but at 'computics' as another tool of analyzingphenomena. It is a great challenge for talented younger students to commit such a novel,exciting interdisciplinary field as a 'Simulation Scientist', experienced by rich computationalfacilities and fine course work provided by JAIST.
