A Caveat on Building Nonlocal Models of Cosmology
N. C. Tsamis, R. P. Woodard
Nonlocal models of cosmology might derive from graviton loop corrections to the effective field equations from the epoch of primordial inflation. Although the Schwinger-Keldysh for…

Observational Viability and Stability of Nonlocal Cosmology
S. Deser, R. P. Woodard
We show that a class of nonlocal gravity models, proposed to explain current cosmic acceleration without dark energy, passes two major tests: First, they can be defined so as not t…

Stochastic Samples versus Vacuum Expectation Values in Cosmology
N. C. Tsamis, Aggelos Tzetzias, R. P. Woodard
Particle theorists typically use expectation values to study the quantum back-reaction on inflation, whereas many cosmologists stress the stochastic nature of the process. While ex…
