Figure 1: The quantum efficiency network.
From: Structure–dynamics relationship in coherent transport through disordered systems
(a) Nodes in the network represent structures with six excitable sites (N=6) and ε>0.09. Links are placed if two structures are geometrically similar. The network layout is obtained via the Fruchterman–Reingold algorithm25, which puts nodes with several neighbours in common close in space. To avoid overcrowding in the network layout, only one-fifth of the nodes have been represented in the picture. Node size is proportional to the number of links. (b) The probability distribution of efficiency loss upon random displacements for the eight clusters (calculated on the whole sample, see main text for details). All eight distributions are shown where colours are chosen to highlight the presence of three classes (lines are a guide to the eye). Network nodes colour coding follows the class definitions: pair (red), inline (blue) and sparse (yellow).
