Finite relative entropy for locally squeezed states
Daniela Cadamuro, Markus B. Fröb, Dimitrios Katsinis +1
Relative entropy serves as a fundamental measure of state distinguishability in both quantum information theory and relativistic quantum field theory. Despite its conceptual import…
Measurements in stochastic gravity and thermal variance
Markus B. Fröb, Dražen Glavan, Paolo Meda
We analyze the thermal fluctuations of a free, conformally invariant, Maxwell quantum field (photon) interacting with a cosmological background spacetime, in the framework of quant…
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…
