Quantum Cosmology in Accelerating Spacetimes II

S. P. Miao, N. C. Tsamis, R. P. Woodard

This paper is a sequel in which we further analyze the recently derived quantum gravity equations which apply in accelerating cosmological spacetimes and whose solutions should be…

Cancellation of one-parameter graviton gauge dependence in the effective scalar field equation in de Sitter

Dražen Glavan, Shun-Pei Miao, Tomislav Prokopec +1

We investigate gauge dependence of one-graviton-loop corrections to the effective field equation of the massless, minimally coupled scalar in de Sitter, obtained by including sourc…

Sub-Leading Logarithms for Scalar Potential Models on de Sitter

S. P. Miao, N. C. Tsamis, R. P. Woodard

The continual production of long wavelength scalars and gravitons during inflation injects secular growth into loop corrections which would be constant in flat space. One typically…

Quantum Cosmology in Accelerating Spacetimes

S. P. Miao, N. C. Tsamis, R. P. Woodard

We simplify the gravitational equations which apply in accelerating spacetimes and are consistent with the cosmological principle. Solutions to these equations should be tantamount…

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…
