Dark Atoms: Asymmetry and Direct Detection
  We present a simple UV completion of Atomic Dark Matter (aDM) in which heavy
right-handed neutrinos decay to induce both dark and lepton number densities.
This model addresses several outstanding cosmological problems: the
matter/anti-matter asymmetry, the dark matter abundance, the number of light
degrees of freedom in the early universe, and the smoothing of small-scale
structure. Additionally, this realization of aDM may reconcile the CoGeNT
excess with recently published null results and predicts a signal in the CRESST
Oxygen band. We also find that, due to unscreened long-range interactions, the
residual un recombined dark ions settle into a diffuse isothermal halo.
