title = "Stochastic spin flips in polariton condensates: nonlinear tuning from GHz to sub-Hz",
abstract = "The stability of spin of macroscopic quantum states to intrinsic noise is studied for non-resonantly-pumped optically-trapped polariton condensates. We demonstrate flipping between the two spin-polarised states with >104 slow-down of the flip rate by tuning the optical pump power. Individual spin flips faster than 50 ps are time resolved using single-shot streak camera imaging. We reproduce our results within a mean-field model accounting for cross-spin scattering between excitons and polaritons, yielding a ratio of cross-to co-spin scattering of similar to ∼0.6, in contrast with previous literature suggestions.",
