On the importance of radiation-era initial conditions for tensor perturbations

Dražen Glavan, Juraj Klarić, Philipp Klose +1

Conservation of super-horizon tensor fluctuations is crucial for connecting inflation to observations. Starting from first principles, recent works have found violations of this co…

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…

Critical reassessment of the restricted Weyl symmetry

Dražen Glavan, Ruggero Noris, Tom Zlosnik

A class of globally scale-invariant scalar-tensor theories have been proposed to be invariant under a larger class of transformations that take the form of local Weyl transformatio…

Photon propagator for inflation in the general covariant gauge

Silvije Domazet, Dražen Glavan, Tomislav Prokopec

Photon propagator for power-law inflation is considered in the general covariant gauges within the canonical quantization formalism. Photon mode functions in covariant gauges are c…

Gauge Independent Logarithms from Inflationary Gravitons

D. Glavan, S. P. Miao, T. Prokopec +1

Dependence on the graviton gauge enters the conventional effective field equations because they fail to account for quantum gravitational correlations with the source which excites…
