Quantum Scalar Corrections to the Gravitational Potentials on de Sitter Background

Sohyun Park, Tomislav Prokopec, R. P. Woodard

We employ the graviton self-energy induced by a massless, minimally coupled (MMC) scalar on de Sitter background to compute the quantum corrections to the gravitational potentials…

One-loop quantum electrodynamic correction to the gravitational potentials on de Sitter spacetime

C. L. Wang, R. P. Woodard

We compute the one-loop photon contribution to the graviton self-energy on a de Sitter background and use it to solve the linearized Einstein equation for a point mass. Our results…

Quantum Gravity: A Brief History of Ideas and Some Prospects

Steven Carlip, Dah-Wei Chiou, Wei-Tou Ni +1

We present a bird's-eye survey on the development of fundamental ideas of quantum gravity, placing emphasis on perturbative approaches, string theory, loop quantum gravity, and bla…

Precision Predictions for the Primordial Power Spectra of Scalar Potential Models of Inflation

D. J. Brooker, N. C. Tsamis, R. P. Woodard

We exploit a new numerical technique for evaluating the tree order contributions to the primordial scalar and tensor power spectra for scalar potential models of inflation. Among o…

Some Inconvenient Truths

R. P. Woodard

A recent paper by Fröb employs the linearized Weyl-Weyl correlator to construct the tensor power spectrum. Although his purpose was to argue that infrared divergences and secular g…

Fine Tuning May Not Be Enough

S. P. Miao, R. P. Woodard

We argue that the fine tuning problems of scalar-driven inflation may be worse than is commonly believed. The reason is that reheating requires the inflaton to be coupled to other…
