中文摘要 | We analyze theoretically the pumped spin current and its shot noise spectra in a two-level quantum dot system, where the dot is irradiated by circularly polarized light. The device operates at a certain chemical potential configuration in the absence of magnetic field and ferromagnetic spin injection. The spin-resolved shot noise can be modulated by the light nonmonotonously and always indicates a sub-Poissonian type. |
