Relating the modular Hamiltonian to two-point functions
Markus B. Fröb
We consider the modular Hamiltonian associated to standard subspaces for a free scalar field in a globally hyperbolic spacetime in an arbitrary Gaussian state. We show how the modu…
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…
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…
Mode-sum construction of the covariant graviton two-point function in the Poincaré patch of de Sitter space
Markus B. Fröb, Atsushi Higuchi, William C. C. Lima
We construct the graviton two-point function for a two-parameter family of linear covariant gauges in n-dimensional de Sitter space. The construction is performed via the mode-sum…
