DESCRIPTION:Following a recent proposal based on holography the physics of
the very early universe can be described in terms of a three-dimensional
quantum field theory without gravity. In this model cosmological observabl
es are expressed in terms of correlation functions of the energy-momentum
tensor computed in the QFT. Testing the model against observational data\,
e.g. from Planck\, requires control over the non-perturbative dynamics in
the QFT\, which we address with numerical simulations on the lattice. In
this talk I will discuss our progress towards making predictions for the p
roperties of the CMB from our model\, which requires understanding the IR
properties of 3d super-renormalisable QFT and the computation of 2pt funct
ions of the energy-momentum tensor on the lattice.\n\nhttps://indico.desy.
