论文摘要
对经过周期性激光脉冲列车的量子点中自旋动力学的大规模模拟，使我们能够描述和理解相关的实验。通过将不同模型的数据与实验结果进行比较，我们对相关物理机制有了改进的了解。使用复杂的数值方法和有效的实现与外推参数相结合，在实际实验中，与接近的参数范围达到了非平衡固定状态。借助高性能计算，我们可以调整实验参数，以指导未来的实验研究。重要的是，我们的模拟揭示了在法拉第几何形状中谐振自旋扩增的可能性，即当将纵向磁场应用于量子点时。
Large-scale simulations of the spin dynamics in quantum dots subjected to trains of periodic laser pulses enable us to describe and understand related experiments. By comparing the data for different models to experimental results, we gain an improved understanding of the relevant physical mechanisms. Using sophisticated numerical approaches and an efficient implementation combined with extrapolation arguments, nonequilibrium stationary states are reached for parameter ranges close to the ones in real experiments. With the help of high performance computing, we can tune the experimental parameters to guide future experimental research. Importantly, our simulations reveal the possibility of resonant spin amplification in Faraday geometry, i.e., when a longitudinal magnetic field is applied to the quantum dots.
