Exact 1-loop corrections from matter loops enhance the decay of gravitational wave mode functions after horizon crossing during inflation, with stronger effects from minimally coupled scalars possibly interpreted as a shift in the Hubble parameter.

abstract
We revive an old result, that one-loop corrections to the graviton propagator induce 1/r^3 corrections to the Newtonian gravitational potential, and compute the coefficient due to closed loops of the U(N) {\cal N}=4 super-Yang-Mills theory that arises in Maldacena's AdS/CFT correspondence. We find exact agreement with the coefficient appearing in the Randall-Sundrum brane-world proposal. This provides more evidence for the complementarity of the two pictures.
