Using molecular dynamics simulation, we examine the dynamics of crystal, polycrystal, and glass in a Lennard-Jones binary mixture composed of small and large particles in two dimensions. The...
Structural and dynamical heterogeneities in two-dimensional melting (2008)
Shiba, Hayato, Onuki, Akira, Araki, Takeaki
Using molecular dynamics simulation, we study structural and dynamical heterogeneities at melting in two-dimensional one-component systems with 36000 particles. Between crystal and liquid we find...
Anomalous Heat Conduction in Three-Dimensional Nonlinear Lattices (2007)
Heat conduction in three-dimenisional nonlinear lattice models is studied using nonequilibrium molecular dynamics simulations. We employ the FPU model, in which there exists a nonlinearity in the...
Elastic Convection in Vibrated Viscoplastic Fluids (2006)
Shiba, Hayato, Ruppert-Felsot, Jori, Takahashi, Yoshiki, Murayama, Yoshihiro, Ouyang, Qi, Sano, Masaki
We observe a new type of behavior in a shear thinning yield stress fluid: freestanding convection rolls driven by vertical oscillation. The convection occurs without the constraint of container...
Divergent Thermal Conductivity in Three-dimensional Nonlinear lattices (2006)
Shiba, Hayato, Yukawa, Satoshi, Ito, Nobuyasu
Heat conduction in three-dimensional nonlinear lattices is investigated using a particle dynamics simulation. The system is a simple three-dimensional extension of the Fermi-Pasta-Ulam $\beta$...
