(color online) Spin conductance as a function of kl (a) when a chain of hexagons is connected at the nodes (m = 3), (b) when a chain of squares is connected along segments (m = 3). The strengths of the RSOC and the DSOC have the same value α_R = α_D = 0.02π. Note that the total conductance for a chain without SOC overlaps the lines for G_total.
