P. Delosrios et al., SELF-ORGANIZED CRITICALITY IN DETERMINISTIC SYSTEMS WITH DISORDER, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 57(6), 1998, pp. 6451-6459
Using the Bak-Sneppen model of biological evolution as our paradigm, w
e investigate in which cases noise can be substituted with a determini
stic signal without destroying self-organized criticality (SOC). If th
e deterministic signal is chaotic the universality class is preserved;
some nonuniversal features, such as the threshold, depend on the time
correlation of the signal. We also show that, if the signal introduce
d is periodic, SOC is preserved but in a different universality class,
as long as the spectrum of frequencies is broad enough.
