Description
We consider a real scalar field in de Sitter background and compute its thermal propagators.
We propose that non-trivial thermal effects in the |out⟩ vacuum can be encoded in the anomalous
dimensions of the d = 3 Ising model. One of these anomalous dimensions, the critical exponent
η, fixes completely a number of cosmological observables, which we compute.
