A nonequilibrium-potential approach to competition in neural populations
R. R. Deza, J. I. Deza, N. Martinez +2
Energy landscapes are a useful aid for the understanding of dynamical systems, and a valuable tool for their analysis. For a broad class of rate models of neural networks, we deriv…
Complete synchronization of convective patterns between Gray-Scott systems
Gonzalo G. Izús, Roberto R. Deza, Luis Bernal +1
Two identical 1D autocatalytic systems with Gray--Scott kinetics--driven towards convectively unstable regimes and submitted to independent spatiotemporal Gaussian white noises--ar…
Aspects of stochastic resonance in reaction-diffusion systems: The nonequilibrium-potential approach
Horacio S. Wio, Roberto R. Deza
We analyze several aspects of the phenomenon of stochastic resonance in reaction-diffusion systems, exploiting the nonequilibrium potential's framework. The generalization of this…
Enhancement of Stochastic Resonance in distributed systems due to a selective coupling
B. von Haeften, R. Deza, H. S. Wio
Recent massive numerical simulations have shown that the response of a "stochastic resonator" is enhanced as a consequence of spatial coupling. Similar results have been analytical…
Nonequilibrium phase transitions induced by multiplicative noise: effects of self-correlation
S. E. Mangioni, R. R. Deza, R. Toral +1
A recently introduced lattice model, describing an extended system which exhibits a reentrant (symmetry-breaking, second-order) noise-induced nonequilibrium phase transition, is st…
Disordering effects of color in nonequilibrium phase transitions induced by multiplicative noise
S. Mangioni, R. Deza, H. S. Wio +1
The model introduced by Van den Broeck, Parrondo and Toral [Phys. Rev. Lett.73, 3395 (1994)] -- leading to a second-order-like noise-induced nonequilibrium phase transition which s…
