  • Flat space cosmologies in two dimensions: Phase transitions and asymptotic mass domination 
    BAGCHI, ARJUN; Grumiller, Daniel; Salzer, Jakob; Sarkar, Sourav; Scholler, Friedrich (American Physical Society, 2014-10)
    We study flat space cosmologies in two dimensions by taking the flat space limit of the Achúcarro-Ortiz model. We unravel a phase transition between hot flat space and flat space cosmologies, and derive a new dilaton-dependent ...
