Dynamics of k-core percolation in a random graph
Mami Iwata, Shin-ichi Sasa
We study the edge deletion process of random graphs near a k-core percolation point. We find that the time-dependent number of edges in the process exhibits critically divergent fl…
Scale-free patterns at a saddle-node bifurcation in a stochastic system
Mami Iwata, Shin-ichi Sasa
We demonstrate that scale-free patterns are observed in a spatially extended stochastic system whose deterministic part undergoes a saddle-node bifurcation. Remarkably, the scale-f…
Critical phenomena in globally coupled excitable elements
Hiroki Ohta, Shin-ichi Sasa
Critical phenomena in globally coupled excitable elements are studied by focusing on a saddle-node bifurcation at the collective level. Critical exponents that characterize diverge…
Representation of nonequilibrium steady states in large mechanical systems
Teruhisa S. Komatsu, Naoko Nakagawa, Shin-ichi Sasa +1
Recently a novel concise representation of the probability distribution of heat conducting nonequilibrium steady states was derived. The representation is valid to the second order…
