Spin noise correlations in multispecies hot atomic vapors

Abstract

Spin-exchange collisions in alkali-metal vapors underlie several fundamental and applied investigations such as nuclear structure studies and tests of fundamental symmetries, ultrasensitive atomic magnetometers, magnetic resonance, and biomagnetic imaging. The effect of spin-exchange collisions on the atomic system is very rich and it can vary depending on the conditions: it can cause decoherence and produce spin noise, or it can transfer spin-polarization and coherences without contributing to spin relaxation. Recently, with the development of quantum measurements and quantum technology in general, spin-exchange collisions have attracted a lot of interest as a resource for quantum metrology and as a potential source of quantum noise. We have performed a precision experiment regarding spin-noise correlations in multispecies hot alkali vapors. In particular, we observe non-zero spin-noise correlations and coherence transfer effects in equilibrium between overlapping 133Cs and 87Rb spin ...
