Author(s): Niayesh Afshordi and Elliot Nelson We study the influence of the fluctuations of a Lorentz-invariant and conserved vacuum on cosmological metric perturbations, and show that they generically blow up in the IR. We compute this effect using the Källén-Lehmann spectral representation of stress correlators in generic quantum field theori… [Phys. Rev. D 93, 083505] Published Thu Apr 07, 2016
