Ordering-Independent Wheeler-DeWitt Equation for Flat Minisuperspace Models
Victor Franken, Eftychios Kaimakkamis, Hervé Partouche +1
We consider minisuperspace models with two-derivative kinetic terms, assuming a flat target space and a closed Universe. We show that, upon canonical quantization of the Hamiltonia…
The exact Wheeler-DeWitt equation for the scale-factor minisuperspace model
Eftychios Kaimakkamis, Hervé Partouche, Karunava Sil +1
We consider the classical minisuperspace model describing a closed, homogeneous and isotropic Universe, with a positive cosmological constant. Upon canonical quantization, the infi…
Closed FRW holography: A time-dependent ER=EPR realization
Victor Franken, Hervé Partouche, François Rondeau +1
We extend a recent de Sitter holographic proposal and entanglement entropy prescription to generic closed FRW cosmologies in arbitrary dimensions, and propose that for large classe…
Bridging the static patches: de Sitter holography and entanglement
Victor Franken, Hervé Partouche, François Rondeau +1
In the context of de Sitter static-patch holography, two prescriptions have been put forward for holographic entanglement entropy computations, the monolayer and bilayer proposals.…
A unimodular-like string effective description
Alex Kehagias, Hervé Partouche, Nicolaos Toumbas
We show that vanishing of the sigma-model beta-functions for the metric , antisymmetric tensor and dilaton of any string-theory model in dimensions at tree…
Probability distribution for the quantum universe
Alex Kehagias, Hervé Partouche, Nicolaos Toumbas
We determine the inner product on the Hilbert space of wavefunctions of the universe by imposing the Hermiticity of the quantum Hamiltonian in the context of the minisuperspace mod…
