Elimination of spiral chaos by periodic force for the Aliev-Panfilov model
Hidetsugu Sakaguchi, Takefumi Fujimoto
Spiral chaos appears in the two dimensional Aliev-Panfilov model. The generation mechanism of the spiral chaos is related to the breathing instability of pulse trains. The spiral c…

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…
