Coherent control of the electronic and nuclear spins in quantum dot ensembles (A04)

这个项目的目的是定量描述驱动量子点中的自旋动力学。将结合前一阶段开发的不同模拟技术来研究不同的g因子、不同的超精细耦合，特别是在系综的每个量子点中不同的激发能量的影响。此外，量子点之间的长程自旋-自旋相互作用的起源及其对自旋动力学的影响将被阐明。我们打算研究不同的脉冲形状和脉冲串的影响，以利用定制的脉冲序列进行相干自旋操纵。

This project aims for a quantitative description of the spin dynamics in driven quantum dots. The different simulation techniques developed in the previous period will be combined to study the effects of different g-factors, different hyperfine couplings and in particular different excitation energies in each quantum dot of the ensemble. Furthermore, the origin of the still not understood long-range spin-spin interaction between QDs and its impact on the spin dynamics will be clarified. We intend to investigate the influence of different pulse shapes and pulse trains to exploit tailored pulse sequences for coherent spin manipulations.
