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

本项目旨在定量描述驱动量子点的自旋动力学。本文将结合前人发展的不同模拟技术，研究不同的g因子、不同的超精细耦合，特别是不同激发能对系综量子点的影响。此外，还将阐明量子点之间的远程自旋-自旋相互作用的起源及其对自旋动力学的影响。我们打算研究不同脉冲形状和脉冲序列对相干自旋操作的影响，以开发定制的脉冲序列。

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.
