Abstract
The phase ordering dynamics of coupled chaotic maps on
fractal networks are investigated. The statistical properties
of the systems are characterized by means of the persistence
probability of equivalent spin variables that define the
phases. The persistence saturates and phase domains freeze
for all values of the coupling parameter as a consequence of
the fractal structure of the networks, in contrast to the
phase transition behavior previously observed in regular
Euclidean lattices. Several discontinuities and other
features found in the saturation persistence curve as a
function of the coupling are explained in terms of changes
of stability of local phase configurations on the fractals.
