    A Lower Bound on Dark Matter Mass
    (American Physical Society, 2024) Amin, Mustafa A.; Mirbabayi, Mehrdad
    We argue that there is a lower bound of order 10−19 eV on dark matter mass if it is produced after inflation via a process with finite correlation length. We rely on nondetection of free-streaming suppression and white-noise enhancement of density perturbations as the observational inputs.
