RESEARCH INTERESTS
The research interests in our group are mainly focus on exploring phase equilibria and phase transitions between liquids and solids, dynamics and structure of liquids, properties of crystalline and amorphous solids, and surface phenomena, with statistical mechanics, thermodynamics, and computer simulation as the "instrument". An infrastructure consists of hundreds of processors are running every second to support our exploration.
Topics which have been studied so far are:
- Structure and dynamics of water and aqueous solutions
- Thermodynamic stability of hydrogen-bonded network systems such as clathrate hydrate.
- Phase transitions and critical phenomena
- Bulk and inhomogeneous fluids
- Nucleation, crystallization, and fusion of water and in the aqueous solutions
- Fluids and solids in confined geometry
- Surface tension
- Hydrophobic effect.

- Liquid-Liquid Separation of Aqueous Solutions: A Molecular Dynamics Study
Last update: June 24, 2019
In the liquid-liquid phase transition scenario, supercooled water separates into the high density liquid (HDL) and low density liquid (LDL) phases at temperatures lower than the second critical point. ... - A Bayesian Approach for Identification of Ice Ih, ice Ic, High Density and Low Density Liquid Water with a Torsional Order Parameter

A new paper from our group has been published. Masakazu Matsumoto, Takuma Yagasaki, and Hideki Tanaka A Bayesian Approach for Identification of Ice Ih, ice Ic, High Density and Low Density L ... - Negative Thermal Expansivity of Ice: Comparison of the Monatomic mW Model with the All-Atom TIP4P/2005 Water Model
Last update: May 15, 2019
Ordinary substances shrink as the temperature decreases, but ice expands at very low temperatures. This phenomenon, called the negative thermal expansion of ice, is one of the abnormal properties of water ... - Molecular dynamics study of kinetic hydrate inhibitors: The optimal inhibitor size and effect of guest species
Last update: January 29, 2019
Kinetic hydrate inhibitors (KHIs) are water soluble polymers that bind to the hydrate surface and ratard crystal growth. Experimental studies have shown that small oligomres inhibit hydrate growth efficiently ... - Phase diagram of ice polymorphs under negative pressure considering the limits of mechanical stability
Last update: January 29, 2019
Although the most stable phase in the negative pressure region (in a stretched state) is a gas phase, the crystal can also exist as a metastable state. Regarding water, crystal ice XVI with lower density ...
