Minimal Model of Stochastic Athermal Systems: Origin of Non-Gaussian Noise
Kiyoshi Kanazawa, Tomohiko G. Sano, Takahiro Sagawa +1
For a wide class of stochastic athermal systems, we derive Langevin-like equations driven by non-Gaussian noise, starting from master equations and developing a new asymptotic expa…
Energy pumping in electrical circuits under avalanche noise
Kiyoshi Kanazawa, Takahiro Sagawa, Hisao Hayakawa
We theoretically study energy pumping processes in an electrical circuit with avalanche diodes, where non-Gaussian athermal noise plays a crucial role. We show that a positive amou…
Behavior of pressure and viscosity at high densities for two-dimensional hard and soft granular materials
Michio Otsuki, Hisao Hayakawa, Stefan Luding
The pressure and the viscosity in two-dimensional sheared granular assemblies are investigated numerically. The behavior of both pressure and viscosity is smoothly changing qualita…
