The Other ADM
R. P. Woodard, B. Yesilyurt
In the peculiar manner by which physicists reckon descent, this article is by a "child" and "grandchild" of the late Stanley Deser. We begin by sharing reminiscences of Stanley fro…
The Third Structure Function
S. P. Miao, N. C. Tsamis, R. P. Woodard +1
We re-consider the graviton self-energy induced by a loop of massless, minimally coupled scalars on de Sitter background. On flat space background it can be represented as a sum of…
The Need to Renormalize the Cosmological Constant
N. C. Tsamis, R. P. Woodard, B. Yesilyurt
We consider the massless, minimally coupled scalar on de Sitter background. Although the 1-loop divergences of the graviton 1PI 2-point function are canceled by the usual Weyl ($C^…
Large Inflationary Logarithms in a Nontrivial Nonlinear Sigma Model
C. Litos, R. P. Woodard, B. Yesilyurt
Loops of inflationary gravitons are known to induce large temporal and spatial logarithms which can cause perturbation theory to break down. Nonlinear sigma models possess the same…
Remembrance of Things Past
R. P. Woodard, B. Yesilyurt
Nonlinear sigma models on de Sitter background have proved a useful prototype for quantum gravity in summing the large logarithms which arise from loop corrections. We consider a m…
Unfinished Business in A Nonlinear Sigma Model on de Sitter Background
R. P. Woodard, B. Yesilyurt
Nonlinear sigma models on de Sitter background possess the same kind of derivative interactions as gravity, and show the same sorts of large spacetime logarithms in correlation fun…
