  Stress in dense granular materials and other athermal particle aggregates is
transmitted through a visually striking subnetwork of interparticle contacts,
the filamentary segments of which are referred to as force chains. The
emergence of such preferred subnetwork in structurally disordered media with
constituents interacting primarily by physical contact is not fully understood.
In this work, we study locally correlated transport in Random Geometric Graphs
(RGGs), and show the spontaneous emergence of preferred subnetwork. Our
findings reveal that, despite structural disorder, system spanning localization
of fluxes transmitted through a spatial network can emerge from short ranged
correlations. The spatial and statistical features of the subnetwork are
surprisingly similar to the strong force network in simulated grain assemblies,
and provides insights on the structure and spatial scale of significance of the
force chains.
