Localized coherence in two interacting populations of social agents
arXiv:1309.5998 · doi:10.1016/j.physa.2013.12.035
Abstract
We investigate the emergence of localized coherent behavior in a system consisting of two populations of social agents possessing a condition for non-interacting states, mutually coupled through global interaction fields. As an example of such dynamics, we employ Axelrod's model for social influence. The global interaction fields correspond to the statistical mode of the states of the agents in each population. We find localized coherent states for some values of parameters, consisting of one population in a homogeneous state and the other in a disordered state. This situation can be considered as a social analogue to a chimera state arising in two interacting populations of oscillators. In addition, other asymptotic collective behaviors appear depending on parameter values: a common homogeneous state, where both populations reach the same state; different homogeneous states, where both population reach homogeneous states different from each other; and a disordered state, where both populations reach inhomogeneous states.
