  We develop a unified model of darkgenesis and baryogenesis involving strongly
interacting dark quarks, utilizing the gravitational anomaly of chiral gauge
theories. In these models, both the visible and dark baryon asymmetries are
generated by the gravitational anomaly induced by the presence of chiral
primordial gravitational waves. We provide a concrete model of an SU(2) gauge
theory with two massless quarks. In this model, the dark quarks condense and
form a dark baryon charge superfluid (DBS), in which the Higgs-mode acts as
cold dark matter. We elucidate the essential features of this dark matter
scenario and discuss its phenomenological prospects.
