Anomalous noise spectra in a spin-exchange-relaxation-free alkali-metal vapor

Year: 2024

Type: article

Abstract: The authors perform spin-noise spectroscopy on an unpolarized ${}^{87}$Rb vapor in the spin-exchange-relaxation-free regime and observe noise spectral distributions that deviate strongly from Lorentzian models that accurately describe lower-density regimes. This observation shows that new kinds of information can be extracted from noise spectra and may improve atomic vapor sensors.
