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…
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…
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…
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…
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…
