In this paper we investigated the dynamics of an electron in the presence of a time-dependent laser field in a model potential for a two-level single-electron semiconductor quantum dot (QD) that is capable of undergoing interatomic Coulombic decay (ICD) together with an electron bound to a neighboring QD. We demonstrate that ICD can be initiated by coupling the two-level QD to either a continuous or a pulsed moderate to strong laser and we obtain the total and partial decay widths of the resonance excited state in agreement with that from the solely decay of the resonance [A. Bande, K. Gokhberg, and L. S. Cederbaum, J. Chem. Phys. 135, 144112 (2011)]. A detailed discussion of the effects of direct ionization by the laser in single- or multi-photon process as well as Rabi oscillations is furthermore presented.
在本文中，我们研究了在一个能够经历原子间库仑衰变 (ICD) 的双能级单电子半导体量子点 (QD) 的模型势中，存在时变激光场时电子的动力学。我们证明，通过将双能级 QD 与连续或脉冲强激光耦合，可以引发 ICD，并且我们得到的共振激发态的总衰减宽度和部分衰减宽度与仅通过共振衰变得到的结果一致 [A. Bande, K. Gokhberg, and L. S. Cederbaum, J. Chem. Phys. 135, 144112 (2011)]。此外，还进一步讨论了激光在单光子或多光子过程中的直接电离以及拉比振荡的影响。
