Tip Oscillation of Dendritic Patterns in a Phase Field Model
Hidetsugu Sakaguchi, Seiji Tokunaga
We study dendritic growth numerically with a phase field model. Tip oscillation and regular side-branching are observed in a parameter region where the anisotropies of the surface…

Stick-Slip Motion and Phase Transition in a Block-Spring System
Hidetsugu Sakaguchi
We study numerically stick slip motions in a model of blocks and springs being pulled slowly. The sliding friction is assumed to change dynamically with a state variable. The trans…

Stochastic synchronization in globally coupled phase oscillators
Hidetsugu Sakaguchi
Cooperative effects of periodic force and noise in globally Cooperative effects of periodic force and noise in globally coupled systems are studied using a nonlinear diffusion equa…
