Unified signal response for stochastic resonance in bistable systems
Cong Liu, Xin-Ze Song, Zhi-Xi Wu +1
The phenomenon of stochastic resonance, wherein the stimulus-response of a system can be maximized by an intermediate level of noise, has been extensively investigated through line…
Optimizing and reducing stochastic resonance by noise color in globally coupled bistable systems
Cong Liu, Xin-Ze Song, Zhi-Xi Wu +1
We investigate the collective signal response of two typical nonlinear dynamical models, the mean-field coupled overdamped bistable oscillators and the underdamped Duffing oscillat…
Resonance induced by higher-order coupling diversity
Cong Liu, Chong-Yang Wang, Zhi-Xi Wu +1
The studies of collective oscillations induced by higher-order interactions point out the necessity of group effect in coupling modelization. As yet the related advances are mainly…
Game-environment feedback dynamics for voluntary prisoner's dilemma games
Bin-Quan Li, Cong Liu, Zhi-Xi Wu +1
Recently, the eco-evolutionary game theory which describes the coupled dynamics of strategies and environment have attracted great attention. At the same time, most of the current…
