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. 

Theory of optically detected spin noise in nanosystems

The theory of spin noise in low-dimensional systems and bulk semiconductors is reviewed. Spin noise is usually detected by optical means continuously measuring the rotation angle of the polarization

Spatiotemporal Spin Noise Spectroscopy.

We report on the potential of a new spin noise spectroscopy approach by demonstrating all-optical probing of spatiotemporal spin fluctuations. This is achieved by homodyne mixing of a spatially

Spin-noise spectrum in a pulse-modulated field.

This study measures the spin noise spectrum of a thermal Rubidium vapor in a pulse-modulated transverse magnetic field and develops a simple theory to describe the main structure of the SNS, which consists of resonances centered at half-odd-integer multiples of the modulation frequency while revealing the spin dynamics of the system in a zero field.

Theory of spin noise in nanowires.

It is demonstrated that the spin relaxation can be very slow, and the resulting noise power spectrum increases algebraically as the frequency goes to zero, which makes spin phenomena in nanowires best suitable for studies by rapidly developing spin-noise spectroscopy.

It is found that the noise power spectrum of conducting electrons experiences a shift, which is proportional to the strength of the spin-orbit coupling for electrons moving along the electric field direction.
