    • Dynamical Compactification from de Sitter Space 

      Carroll, Sean M.; Johnson, Matthew C.; Randall, Lisa (Springer, 2009)
      We show that \(D\)-dimensional de Sitter space is unstable to the nucleation of non-singular geometries containing spacetime regions with different numbers of macroscopic dimensions, leading to a dynamical mechanism of ...
    • Emergent Dark Matter, Baryon, and Lepton Numbers 

      Cui, Yanou; Randall, Lisa; Shuve, Brian James (Springer, 2011)
      We present a new mechanism for transferring a pre-existing lepton or baryon asymmetry to a dark matter asymmetry that relies on mass mixing which is dynamically induced in the early universe. Such mixing can succeed with ...
