Heat generation by spin-polarized current in a quantum dot connected to spin battery and ferromagnetic lead |
(a) Spin-resolved currents, (b) heat generation, and (c) spin-resolved electron occupation numbers on the dot as functions of the dot level for indicated parameters. The temperature and the line-width function are all set to be 0.01 U , with ω q = 0.3 U , λ = 0.6 ω q, and p = 0. |
