Show affiliationsWe study the stability of coherent atomic–molecular states of hybrid Bose–Einstein condensates in the framework of the parametrically coupled Gross–Pitaevskii equations with a weak 'short-correlated' noise, also taking into account the self-interaction effects described by the cubic nonlinearity. We show that the stationary states of the hybrid atomic–molecular condensates are much more robust against the effect of noise than the condensate in the critical regime, describing a complete transformation of the atomic fraction into a molecular condensate, where instability develops essentially faster, with the characteristic time proportional to the logarithm of the noise amplitude.
