Nonlinear Dynamics of the Perceived Pitch of Complex Sounds
Julyan H. E. Cartwright, Diego L. Gonzalez, Oreste Piro
We apply results from nonlinear dynamics to an old problem in acoustical physics: the mechanism of the perception of the pitch of sounds, especially the sounds known as complex ton…
Frozen spatial chaos induced by boundaries
Victor M. Eguiluz, Emilio Hernandez-Garcia, Oreste Piro +1
We show that rather simple but non-trivial boundary conditions could induce the appearance of spatial chaos (that is stationary, stable, but spatially disordered configurations) in…
Noise induced transition from an absorbing phase to a regime of stochastic spatiotemporal intermittency
M. G. Zimmermann, R. Toral, O. Piro +1
We introduce a stochastic partial differential equation capable of reproducing the main features of spatiotemporal intermittency (STI). Additionally the model displays a noise indu…
Dynamics of Elastic Excitable Media
Julyan H. E. Cartwright, Victor M. Eguiluz, Emilio Hernandez-Garcia +1
The Burridge-Knopoff model of earthquake faults with viscous friction is equivalent to a van der Pol-FitzHugh-Nagumo model for excitable media with elastic coupling. The lubricated…
Universality in Three-Frequency Resonances
Julyan H. E. Cartwright, Diego L. Gonzalez, Oreste Piro
We investigate the hierarchical structure of three-frequency resonances in nonlinear dynamical systems with three interacting frequencies. We hypothesize an ordering of these reson…
