(color online) (a) Schematic view of the parallel triple dot device connected to source (S) and drain (D) leads. t denotes the inter-dot hopping. (b) Charge occupation on each dot , and (c) Spin correlation between dots i and j at zero temperature as functions of t for fixed energy level . Here, for dots 1 and 3 are identical for symmetry. The remaining parameters are given by U = 0.1 and Γ = 0.01.
