One-loop electromagnetic correlators of SQED in power-law inflation
Dražen Glavan, Gerasimos Rigopoulos
We examine scalar quantum electrodynamics in power-law inflation space-time, and compute the one-loop correction to electric and magnetic field correlators at superhorizon separati…
Breaking of scaling symmetry by massless scalar on de Sitter
D. Glavan, S. P. Miao, T. Prokopec +1
We study the response of a classical massless minimally coupled scalar to a static point scalar charge on de Sitter. By considering explicit solutions of the problem we conclude th…
Graviton Propagator in a 2-Parameter Family of de Sitter Breaking Gauges
D. Glavan, S. P. Miao, T. Prokopec +1
We formulate the graviton propagator on de Sitter background in a 2-parameter family of simple gauges which break de Sitter invariance. Explicit results are derived for the first o…
Einstein-Gauss-Bonnet gravity in 4-dimensional space-time
Dražen Glavan, Chunshan Lin
In this Letter we present a general covariant modified theory of gravity in space-time dimensions which propagates only the massless graviton and bypasses the Lovelock's…
