The endless journey towards the horizon of a quantum black hole
Victor Franken, Thomas G. Mertens, Bruno de S. L. Torres
It is a problem of great importance in quantum gravity whether quantum effects lead to nontrivial structure near black hole horizons, and if their interiors are emergent features o…
Falling through the horizon of a quantum black hole
Victor Franken, Thomas G. Mertens, Bruno de S. L. Torres
We study quantum-gravitational effects on the response of an infalling detector as it crosses the horizon of a near-extremal black hole in the framework of quantum JT gravity. Thes…
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…
Information-theoretic constraints in quantum gravity and cosmology
Victor Franken
In this dissertation, we review results on quantum information constraints in gravity that are relevant to cosmological models and demonstrate how this approach sheds light on cosm…
Tests of restricted Quantum Focusing and a new CFT bound
Victor Franken, Sami Kaya, François Rondeau +2
The restricted quantum focusing conjecture (rQFC) plays a central role in an axiomatic formulation of semiclassical gravity. Since much hinges on its validity, it is imperative to…
Horizon causality from holographic scattering in asymptotically dS
Victor Franken, Takato Mori
In the AdS/CFT correspondence, a direct scattering in the bulk may not have a local boundary analog. A nonlocal implementation on the boundary requires mutual informatio…
de Sitter Connectivity from Holographic Entanglement
Victor Franken
Considering two antipodal observers in de Sitter space, we illustrate how spacetime connectivity between the holographic screens located on the (stretched) horizons emerges from ho…
On the Quantum Bousso Bound in JT gravity
Victor Franken, François Rondeau
We prove the Strominger-Thompson quantum Bousso bound in the infinite class of conformal vacua in semiclassical JT gravity, with postive or negative cosmological constant. The Bous…
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.…
Pseudo-Nambu-Goldstone bosons and tachyons in flux compactification
Victor Franken
In a six-dimensional gauge theory compactified on a torus with magnetic flux, translational symmetry in the extra dimensions is broken. As a result, a massless Nambu-Goldstone boso…
