Representing the Graviton Self-Energy on de Sitter Background
Katie E. Leonard, Sohyun Park, Tomislav Prokopec +1
We derive a noncovariant but simple representation for the self-energy of a conformally transformed graviton field on the cosmological patch of de Sitter. Our representation involv…
Graviton Corrections to Vacuum Polarization during Inflation
Katie E. Leonard, R. P. Woodard
We use dimensional regularization to compute the one loop quantum gravitational contribution to the vacuum polarization on de Sitter background. Adding the appropriate BPHZ counter…
Why multi-tracer surveys beat cosmic variance
L. Raul Abramo, Katie E. Leonard
Galaxy surveys that map multiple species of tracers of large-scale structure can improve the constraints on some cosmological parameters far beyond the limits imposed by a simplist…
Representing the Vacuum Polarization on de Sitter
Katie E. Leonard, T. Prokopec, R. P. Woodard
Previous studies of the vacuum polarization on de Sitter have demonstrated that there is a simple, noncovariant representation of it in which the physics is transparent. There is a…
Graviton Corrections to Maxwell's Equations
Katie E. Leonard, R. P. Woodard
We use dimensional regularization to compute the one loop quantum gravitational contribution to the vacuum polarization on flat space background. Adding the appropriate BPHZ counte…
