Title: "Frame Dependence of Quantum Corrections in Cosmology"
In the context of cosmological models based on an inflaton field non-minimally coupled to gravity, one can remove the non-minimal coupling by performing a conformal transformation of the metric at the price of a more complicated potential. On a classical level this is just a mathematical trick and the two frames -- the original Jordan frame and the minimally coupled Einstein frame -- are equivalent. The question is now if this still holds at the quantum level. We will answer this question for a very general model by calculating and comparing explicitly the corresponding results at the one-loop level. This model is suitable for most of the cosmological applications.
