Holographic cosmology
  OKC colloquia

Tuesday 23 May 2017
from 13:15 to 14:30
at FA31
Speaker : Kostas Skenderis (Southampton)
Abstract : Holographic cosmology offers a novel framework for describing the very early Universe in which cosmological predictions are expressed in terms of the observables of a three dimensional quantum field theory (QFT). This framework includes conventional inflation, which is described in terms of a strongly coupled QFT, but it also allows for qualitatively new models for the very early Universe, where the dual QFT may be weakly coupled. The new models describe a universe which is non-geometric at early times. In this talk I will provide an introduction to holographic cosmology and compare the predictions of the new modes against cosmological observations. It turns out the new holographic models fit the data just as well as LambdaCDM. (Host: Bo Sundborg)
