Quantum Information Chemistry
Recent development of quantum informational techniques opens a new research direction to chemistry that the quantum chemical calculations for large molecular systems can be performed by quantum computers. Quantum algorithms for chemical researches are demanded by the new era of quantum science.
Molecular Dynamics and Physical Properties of glass forming materials
The properties of materials depend considerably on the dynamics of the atoms and molecules that comprise them. Especially, for amorphous materials which are the glass forming materials, dynamics leading to glass transition governs the property of such materials. The research aim is to develop a molecular-level understanding of dynamics in polymeric materials and low molecular weight glass formers via single molecule microscopy and fluorescence correlation spectroscopy.
