Research fields

1) Molecular simulation of soft materials
Our research is centered on the molecular simulation of soft materials such as molecular liquids, polymer brushes, and dendrimers.
We aim to predict their physical properties with quantitative accuracy using Monte Carlo simulation and nonequilibrium molecular dynamics simulation. The nature of melting transition and the phase diagram of soft spheres under geometrical confinement is also investigated.

2) Numerical study of metamaterial composites
We investigate wave propagation in the composites of metamaterials, and also develop novel numerical method suitable for metamaterials.

3) Nonequilibrium dynamics in Coulomb glass
Nonequilibrium relaxation of Coulomb glass in disordered thin films is investigated by the kinetic Monte Carlo simulation. We numerically confirm aging phenomena in the autocorrelation function in a quasi-two-dimensional system with finite thickness, and clarify the effect of an external electric field on the elongated relaxation time because of aging.

4) Spreading of wavepackets on discrete nonlinear Schrödinger equation
Localization-delocalization transition in a three-dimensional discrete nonlinear Schrödinger equation with random potential is investigated, and the effect of nonlinearity is numerically clarified. A subdiffusive behavior is observed in the three-dimensional system when the nonlinearity of the system is sufficiently strong.

Polymer-nanoparticle composites show the solid-liquid phase transition. A schematic illustration of Monte Carlo method which is suitable for parallel computing.
