Massive scalar's self-mass from gravitons in de Sitter
Dražen Glavan, Shun-Pei Miao, Tomislav Prokopec +1
We compute the fully renormalized one-graviton-loop contribution to the self-mass of a massive scalar field in de Sitter space. The computation is performed using dimensional regul…
Universal Secular External Leg Corrections for Gauge Independent Scalar Self-Mass on de Sitter
D. Glavan, S. P. Miao, T. Prokopec +1
This work concerns a procedure for removing gauge dependence from graviton corrections to the effective field equations for a massless, minimally coupled scalar on de Sitter backgr…
Cosmological properties of black-hole hair in the linearly coupled scalar-Gauss-Bonnet theory
Dražen Glavan, Darío Jaramillo-Garrido
We investigate the superhorizon behavior of scalar hair sourced by black holes in de Sitter spacetime in the linearly coupled shift-symmetric scalar-Gauss-Bonnet theory. Working in…
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…
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…
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…
