Semiclassical Theory of Integrable and Rough Andreev Billiards
W. Ihra, M. Leadbeater, J. L. Vega +1
We study the effect on the density of states in mesoscopic ballistic billiards to which a superconducting lead is attached. The expression for the density of states is derived in t…
Damage-Spreading in Self-Organized Critical Systems
Raffaele Cafiero, Angelo Valleriani, Josè Luis Vega
We study the behavior under perturbations of different versions of Bak-Sneppen (BS) model in 1 + 1 dimension. We focus our attention on the damage-spreading features of the BS mode…
Levy-Nearest-Neighbors Bak-Sneppen Model
R. Cafiero, P. De Los Rios, A. Valleriani +1
We study a random neighbor version of the Bak-Sneppen model, where "nearest neighbors" are chosen according to a probability distribution decaying as a power-law of the distance fr…
Extremal Coupled Map Lattices
Guillermo Abramson, Jose Luis Vega
We propose a model for co-evolving ecosystems that takes into account two levels of description of an organism, for instance genotype and phenotype. Performance at the macroscopic…
