" Path to synchronization in complex networks "



Abstract

We study the synchronizability of complex networks whose degree 
distributions are Poisson or heavy tailed (scale-free).  Our analysis 
is based on the dynamics of the Kuramoto's model in a system of coupled 
oscillators that interact in these topologies.  We investigate the 
evolution of patterns of synchronized oscillators, and connect this 
local information with global measures of synchronization in the 
system.  The results show that, there are values for the intensity of 
the interaction that make degree homogeneous networks more 
synchronizable than heterogeneous networks and vice-versa.  Moreover, 
we study the synchronization transition in scale-free networks that are 
characterized by tunable local properties.  Our study highlights the 
need of exploring the whole phase diagram and not only the stability of 
the fully synchronized state, where most studies have been done up to 
now.
