    • PURE STATES ENTANGLEMENT ENTROPY IN NON COMMUTATIVE 2D DE SITTER SPACE-TIME 

      GHITI, F; AISSAOUI, H (Université des Frères Mentouri Constantine, 2013-12-16)
      The entanglement entropy of pure states is discussed within a cosmological non commutative 2D de Sitter space-time. The obtained results are shown to depend strongly on the sign and values of the non commutativity ...
