Spin-up current and heat generation as functions of the spin bias at the left lead for different values of the temperature in panels (a) and (b), and different values of the spin polarization in the right lead in panels (c) and (d). Other parameters are ω q = 0.3 U , λ = 0.6 ω q, ε d = 0.2 U , and Γ 0 =0.01 U . The spin polarization of the right lead in panels (a) and (b) is zero, and the temperature in panels (c) and (d) is T = 0.01 U .
