Graviton propagator in de Sitter space in a simple one-parameter gauge
Dražen Glavan
We construct the graviton propagator in de Sitter space in a one-parameter family of non-covariant gauges. This family generalizes the simple gauge in which most graviton loop comp…
Spectrum of pure gravity: full Hamiltonian analysis
Will Barker, Dražen Glavan
We perform a full Hamiltonian constraint analysis of pure Ricci-scalar-squared () gravity to clarify recent controversies regarding its particle spectrum. While it is well est…
One-loop correction to primordial tensor modes during radiation era
Markus B. Fröb, Dražen Glavan, Paolo Meda +1
The ability to infer properties of primordial inflation relies on the conservation of the superhorizon perturbations between their exit during inflation, and their re-entry during…
Two simple photon gauges in inflation
Dražen Glavan
Photon propagators for power-law inflation are constructed in two one-parameter families of noncovariant gauges, in an arbitrary number of spacetime dimensions. In both gauges phot…
