If you have a question about this talk, please contact Mike Gunn. We study quantized solutions to the Wheeler de Witt (WdW) equation describing a closed Friedmann-Robertson-Walker universe with a Λ term and a set of massless scalar fields. We show that when Λ ≪1in the natural units and the standard in-vacuum state is considered, either wave function of the universe, Ψ , or its derivative with respect to the scale factor, a , behave as random quasi-classical fields at sufficiently large values of a. The former case is realized when 1 ≪a ≪e Details can be found in this paper http://journals.aps.org/prd/abstract/10.1103/PhysRevD.92.063507 This talk is part of the Theoretical Physics Seminars series. ## This talk is included in these lists:Note that ex-directory lists are not shown. |
