| 中文摘要 | we study electron transport through an aharonov-bohm (ab) interferometer with a noninteracting quantum dot in each of its arms. both a magnetic flux phi threading through the ab ring and the rashba spin-orbit (so) interaction inside the two dots are taken into account. due to the existence of the so interaction, the electrons flowing through different arms of the ab ring will acquire a spin-dependent phase factor in the tunnel-coupling strengths. this phase factor, as well as the influence of the magnetic flux, will induce various interesting interference phenomena. we show that the conductance and the local density of states can become spin polarized by tuning the magnetic flux and the rashba interaction strength. under certain circumstances, a pure spin-up or spin-down conductance can be obtained when a spin-unpolarized current is injected from the external leads. therefore, the electron spin can be manipulated by adjusting the rashba spin-orbit strength and the structure parameters.
