FIG. 1.

A schematic illustration of a parallel coupled multiple triple-quantum-dots device with two nonmagnetic metal leads.

FIG. 2.

The linear conductance spectra of several structures of the parallel coupled multi-tQDs chain for U = 0. (a) and (b) The conductance spectra for the cases of Δ = 0 and Δ = 0.5t 0, respectively, with different chain size N (1-4). (c) The conductance spectra for the structure of the chain size N = 5 with different values of Δ.

FIG. 3.

The linear conductance spectra of the multi-tQDs chain with N = 5 for three different situations. (a) The spin-splitting conductance spectrum for Δ = 0, B = 0.2t 0, and U = 0. (b) The spin-splitting conductance spectrum for Δ = 0.5t 0, B = 0.2t 0, and U = 0. (c) The spin-splitting conductance spectrum for Δ = 0.9t 0, B = 0.2t 0, and U = t 0.
