    "abstract": "We theoretically investigate the effect of anomalous quantum correlations on\nthe light-induced frequency shift in the photoassociation spectrum of a\nBose-Einstein condensate (BEC). Anomalous quantum correlations arise because,\nalthough formed from a pair of zero-momentum condensate atoms, a condensate\nmolecule need not dissociate back to the BEC, but may just as well form a\nnoncondensate atom pair with equal and opposite momentum, i.e., due to rogue\nphotodissociation. The uncorrelated frequency shift of the photoassociation\nspectrum is to the red and linearly dependent on the laser intensity. In\ncontrast, anomalous correlations due to rogue dissociation lead to a\nblueshifted photoassociation spectrum. For sufficiently low light intensities,\nthe rogue blueshift is dominant and proportional to the squareroot of\nintensity.",
