Theory of spin-noise in semiconductor quantum dots (A07)

自旋噪声谱是研究半导体纳米结构中载流子自旋动力学的重要工具，它提供了重要的信息，如退相干机制、相关的耦合和其他参数。在第一阶段，我们在方法上取得了重大的理论进展，从数学证明到高效的数值算法代码，主要应用于两点电子自旋-自旋关联。在第二阶段，我们将通过扩展到目前为止发展的方法来讨论包括所有量子效应、高阶自旋关联和核自旋噪声在内的大型自旋浴。

Spin noise spectroscopy is an essential tool to study the spin dynamics of charge carriers in semiconductor nanostructures yielding important information, e.g. on decoherence mechanisms, relevant couplings and other parameters. In the first period, we achieved significant theoretical progress in methods ranging from mathematical proofs to efficient codes for numerical algorithms, mostly applied to two-point electronic spin-spin correlations. In the second period, we will address large spin baths including all quantum effects, higher-order spin correlations, and nuclear spin noise by extending the so far developed approaches.
