量子点氦中自旋轨道相互作用诱导的单重态-三重态共振拉曼跃迁
Spin-orbit Interaction induced Singlet-Triplet Resonant Raman Transitions in Quantum-dot Helium
摘要：
从我们对双电子量子点（人造氦原子）共振拉曼跃迁的理论研究中，我们发现在这个系统中，只有在存在自旋-轨道相互作用的情况下，才允许单重态-三重态拉曼跃迁（在极化组态中）。随着外加磁场的增加，这种跃迁超过了单重态-单重态和三重态-三重态跃迁。因此，这种有趣的效应可以用来调谐拉曼跃迁以及少电子量子点中的自旋轨道耦合。
英文摘要：
From our theoretical studies of resonant Raman transitions in two-electron quantum dots (artificial helium atoms) we show that in this system, the singlet-triplet Raman transitions are allowed (in polarized configuration) only in the presence of spin-orbit interactions. With an increase of the applied magnetic field this transition dominates over the singlet-singlet and triplet-triplet transitions. This intriguing effect can therefore be utilized to tune Raman transitions as well as the spin-orbit coupling in few-electron quantum dots.
