Functional truncations in asymptotic safety for quantum gravity
Juergen Dietz
Finite dimensional truncations and the single field approximation have thus far played dominant roles in investigations of asymptotic safety for quantum gravity. This thesis is dev…
Fixed point structure of the conformal factor field in quantum gravity
Juergen A. Dietz, Tim R. Morris, Zoe H. Slade
The background independent flow equations for conformally reduced gravity are shown to be equivalent to flow equations naturally adapted to scalar field t…
Background independent exact renormalization group for conformally reduced gravity
Juergen A. Dietz, Tim R. Morris
Within the conformally reduced gravity model, where the metric is parametrised by a function of the conformal factor , we keep dependence on both the background and fluct…
The local potential approximation in the background field formalism
I. Hamzaan Bridle, Juergen A. Dietz, Tim R. Morris
Working within the familiar local potential approximation, and concentrating on the example of a single scalar field in three dimensions, we show that the commonly used approximati…
Redundant operators in the exact renormalisation group and in the f(R) approximation to asymptotic safety
Juergen A. Dietz, Tim R. Morris
In this paper we review the definition and properties of redundant operators in the exact renormalisation group. We explain why it is important to require them to be eigenoperators…
Asymptotic safety in the f(R) approximation
Juergen A. Dietz, Tim R. Morris
In the asymptotic safety programme for quantum gravity, it is important to go beyond polynomial truncations. Three such approximations have been derived where the restriction is on…
