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…

Holography for de Sitter bubble geometries

Anastasios Irakleous, François Rondeau, Nicolaos Toumbas

We generalize the de Sitter static patch holographic proposal and the bilayer holographic entanglement entropy prescription to de Sitter geometries containing a bubble of smaller p…

Anomalous extension of the Standard Model

Pascal Anastasopoulos, Ignatios Antoniadis, Karim Benakli +1

We present a set of example models in which the Standard Model (SM) symmetry group is extended by a new abelian symmetry. This additional symmetry appears anomalous in the effectiv…

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.…
