Relative entropy for in the Rindler wedge
Markus B. Fröb, Albert Much, Kyriakos Papadopoulos
We consider the relative entropy between the vacuum and a coherent state in the Rindler wedge for an interacting theory to first order in . We construct the perturbativel…
De Sitter quantum gravity within the covariant Lorentzian approach to asymptotic safety
Edoardo D'Angelo, Renata Ferrero, Markus B. Fröb
Recent technical and conceptual advancements in the asymptotic safety approach to quantum gravity have enabled studies of the UV completion of Lorentzian Einstein gravity, emphasiz…
Entropy-area law and temperature of de Sitter horizons from modular theory
Edoardo D'Angelo, Markus B. Fröb, Stefano Galanda +3
We derive an entropy-area law for the future horizon of an observer in diamonds inside the static patch of de Sitter spacetime, taking into account the backreaction of quantum matt…
Constructing CFTs from AdS flows
Markus B. Fröb
We study the renormalization group flow equations for correlation functions of weakly coupled quantum field theories in AdS. Taking the limit where the external points approach the…
FieldsX -- An extension package for the xAct tensor computer algebra suite to include fermions, gauge fields and BRST cohomology
Markus B. Fröb
I present the tensor computer algebra package FieldsX, which extends the xAct suite of tensor algebra packages to perform computations in field theory with fermions and gauge field…
One-loop quantum gravitational corrections to the scalar two-point function at fixed geodesic distance
Markus B. Fröb
We study a proposal for gauge-invariant correlation functions in perturbative quantum gravity, which are obtained by fixing the geodesic distance between points in the fluctuating…
