论文摘要
Landau-Zener-Stückelberg-Majorana（LZSM）在Zeeman-SPIT四级系统中的单个旋转状态进化在定期驱动的双量子点中通过Floquet Stroboscopic方法研究了。旋转式和自旋流式隧穿工艺与电动偶极旋转共振（EDSR）之间的相互作用，该偶极旋转共振（EDSR）在单个点中诱导，并通过LZSM多级交叉与相邻量子点增强，并根据微波（MW）频率（MW）频率，驱动速度驱动器，Interdot Detunning和Maintem Detunning和Maintem Mainge Detunning和Maintem Mainge Detunning和Maintem Mainge Detunning和Maintem Maintem detunning和磁性磁盘进行了研究。标识了参数空间中的许多特殊点，其中所有三个特征都合并为其中。在这种三重交叉共振条件下，互截面的隧道与EDSR频率下的每个点的快速旋转演变结合在一起。 EDSR的谐波在旋转依赖性隧道图与可变磁场和MW频率中揭示。该结果适用于具有强旋转轨道相互作用的电子和孔系统，并且可能有助于开发Qubit设备中自旋控制和读数的新的时间效率方案。
Single spin state evolution induced by the Landau-Zener-Stückelberg-Majorana (LZSM) interference in a Zeeman-spit four level system in a periodically driven double quantum dot is studied theoretically by the Floquet stroboscopic method. An interplay between spin-conserving and spin-flip tunneling processes with the Electric Dipole Spin Resonance (EDSR) that is induced in an individual dot and enhanced by the LZSM multiple level crossings with the neighboring quantum dot is investigated as a function of the microwave (MW) frequency, driving amplitude, interdot detuning, and magnetic field. A number of special points in the parameter space are identified, out of which where all the three features are merged. Under this triple-crossing resonance condition the interdot tunneling is combined with a fast spin evolution in each dot at the EDSR frequency. Harmonics of the EDSR are revealed in the spin-dependent tunneling maps versus variable magnetic field and MW frequency. The results are applicable for both electron and hole systems with strong spin-orbit interaction and may be useful for developing new time-efficient schemes of the spin control and readout in qubit devices.
