    • This problem has been studied extensively in the experimental context of cold molecule formation but in the absence of an optical lattice (see Ref.). However, the main result of the current paper, Eq., and the existence of doublons in general rely crucially on the presence of such a lattice.

    • In practice the initial on-site attraction is not infinitely strong and doublons form a thermal distribution in a band with finite bandwidth. However, in typical experiments the temperature greatly exceeds the doublon bandwidth, implying that the distribution is uniform. As a result, the evenly weighted average over the BZ, and hence the power-law survival probability, remains intact.
