Computing the Primordial Power Spectra Directly
Maria G. Romania, N. C. Tsamis, R. P. Woodard
The tree order power spectra of primordial inflation depend upon the norm-squared of mode functions which oscillate for early times and then freeze in to constant values. We derive…
Quantum Gravity and Inflation
M. G. Romania, N. C. Tsamis, R. P. Woodard
We review some perturbative results obtained in quantum gravity in an accelerating cosmological background. We then describe a class of non-local, purely gravitational models which…
Primordial Gravitational Waves Enhancement
Maria G. Romania, N. C. Tsamis, R. P. Woodard
We reconsider the enhancement of primordial gravitational waves that arises from a quantum gravitational model of inflation. A distinctive feature of this model is that the end of…
Possible Enhancement of High Frequency Gravitational Waves
Maria G. Romania, N. C. Tsamis, R. P. Woodard
We study the tensor perturbations in a class of non-local, purely gravitational models which naturally end inflation in a distinctive phase of oscillations with slight and short vi…
