Noise Spectroscopy as a Probe of Condensed Matter Systems

Noise spectroscopies, which measure a system's fluctuations, can offer advantageous scaling with reduced system size and can also disturb the system less as compared with pump-probe measurements. Thus noise spectroscopies can be attractive for the study of small scale systems. A study of stochastic electron spin fluctuations—spin noise—in two physical systems: gases of alkali atoms, and electrons in n-type semiconductors is discussed, as is a theoretical study of the application of noise spectroscopy to ultracold fermionic gases of alkali atoms.
