Optical Resonance Shift Spin Noise Spectroscopy

Abstract
Quantum spin fluctuations provide a unique way to study spin dynamics without system perturbation. Here we put forward an optical resonance shift spin noise spectroscopy as a powerful tool to measure the spin noise of various systems from magnetic impurities in solids to free atoms and molecules. The quantum spin fluctuations in these systems can shift the optical resonances by more than the homogeneous linewidth and produce huge Faraday rotation noise. We demonstrate, that the resonance shift spin noise spectroscopy gives access to the high order spin correlators, which contain complete information about the spin dynamics in contrast with the second order correlator measured by conventional Pauli-blocking spin noise spectroscopy. The high order quantum spin correlators manifest themselves as a comb of peaks in the Faraday rotation noise spectra in transverse magnetic field. This effect is closely related with the multispin flip Raman scattering observed in the Mn-doped nanostructures.
