论文摘要
我们研究了与自旋轨道相互作用的自旋封锁双量子点的AC场诱导的电流峰。 AC场调节了插点隧道耦合或能量失调，我们选择AC场频率范围来诱导两个单线 - 三个曲折跃迁，从而导致两个当前峰。我们表明，对于一个大的失调，当AC场调节隧道耦合时，这两个电流峰可能会明显更强，从而使旋转轨道间隙的检测更加有效。我们还证明了自旋轨道相互作用的时间依赖性的重要性。
We study the AC field induced current peaks of a spin blockaded double quantum dot with spin-orbit interaction. The AC field modulates either the interdot tunnel coupling or the energy detuning, and we choose the AC field frequency range to induce two singlet-triplet transitions giving rise to two current peaks. We show that for a large detuning the two current peaks can be significantly stronger when the AC field modulates the tunnel coupling, thus making the detection of the spin-orbit gap more efficient. We also demonstrate the importance of the time dependence of the spin-orbit interaction.
