@article{Sinitsyn2016TheTO, title={The theory of spin noise spectroscopy: a review.}, author={Nikolai A. Sinitsyn and Yuriy V. Pershin}, journal={Reports on progress in physics. Physical Society}, year={2016}, volume={79 10}, pages={ 106501 } }

Direct measurements of spin fluctuations are becoming the mainstream approach for studies of complex condensed matter, molecular, nuclear, and atomic systems. This review covers recent progress in the field of optical spin noise spectroscopy (SNS) with an additional goal to establish an introduction into its theoretical foundations. Various theoretical techniques that have been recently used to interpret results of SNS measurements are explained alongside examples of their applications.
