Calculated results of the conductance . In the abscissa, to the drain 1 for spin G_{1,± }±1/2 in the impurity Anderson model with three leadsε= (_{d }ε_{1 }+ ε_{2})/2, where ε_{1 }and ε_{2 }are the energy levels in the quantum dot. Solid and broken lines indicate G_{1,+ }and G_{1,-}, respectively. The level broadening by the tunnel coupling to the source and drain
1 is Γ_{S }= Γ_{D1 }≡ Γ (V_{S,1}/V_{S,2 }= 1/2, V_{D1,1}/V_{D1,2 }= -3), whereas that to drain 2 is (a) Γ_{D2 }= 0.2Γ, (b) 0.5Γ, (c) Γ, and (d) 2Γ (V_{D2,1}/V_{D2,2 }= 1). Δε = ε_{2 }- ε_{1 }= 0.2Γ. The strength of SO interaction is Δ_{SO }= 0.2Γ.
