  • Entropy, black holes, and the new cyclic universe 
    Ijjas, Anna; Steinhardt, Paul J. (Amsterdam : North-Holland Publ., 2021)
    We track the evolution of entropy and black holes in a cyclic universe that undergoes repeated intervals of expansion followed by slow contraction and a smooth (non-singular) bounce. In this kind of cyclic scenario, there ...
  • Supersmoothing through slow contraction 
    Cook, William G.; Glushchenko, Iryna A.; Ijjas, Anna; Pretorius, Frans; Steinhardt, Paul J. (Amsterdam : Elsevier B.V., 2020)
    Performing a fully non-perturbative analysis using the tools of numerical general relativity, we demonstrate that a period of slow contraction is a “supersmoothing” cosmological phase that homogenizes, isotropizes and ...
