“…We analyse in detail spin-noise correlations between the two species and we find that even in equilibrium the two atomic systems share and exchange spin-noise correlations that build-up as a result of the spin-exchange interaction. We observe a coherence transfer between the two vapors that is more evident in small magnetic fields and we find that a positive spin-noise correlation at τ = 0 in agreement with the predictions of [89,100,118].…”

“…It is also evident that an initially correlated state remains also correlated after the unitary exchange interaction. This is a first demonstration of the general belief that successive collisions can in principle sustain quantum correlations [83,118].…”

“…Frequent spin-exchange collisions between pairs of atoms in the vapor manifest a local spin-dependent interaction. This interaction often leads to decoherence and relaxation [28] but can also enable coherent coupling and facilitate optical pumping and sensing in various applications [29][30][31][32][33][34][35][36][37][38][39][40][41]. In particular, a pioneering work by Forston et al has demonstrated the emergence of spontaneous spin-polarization and magnetic bi-stability upon absorption of linearly-polarized light [42][43][44].…”
