Holographic Screen Sequestration
Aidan Chatwin-Davies, Pompey Leung, Grant N. Remmen
Holographic screens are codimension-one hypersurfaces that extend the notion of apparent horizons to general (non-black hole) spacetimes and that display interesting thermodynamic…
Covariant Predictions for Planck-Scale Features in Primordial Power Spectra
Aidan Chatwin-Davies, Achim Kempf, Petar Simidzija
In this companion to our letter (arXiv:2208.10514), we elaborate the full details of the predicted corrections to the primordial scalar and tensor power spectra that arise from qua…
Predictions for Quantum Gravitational Signatures from Inflation
Aidan Chatwin-Davies, Achim Kempf, Petar Simidzija
We compute the corrections to the primordial power spectrum that should arise in realistic inflationary scenarios if there exists a generic covariant ultraviolet (UV) cutoff, as co…
Islands in Multiverse Models
Sergio E. Aguilar-Gutierrez, Aidan Chatwin-Davies, Thomas Hertog +2
We consider multiverse models in two-dimensional linear dilaton-gravity theories as toy models of false vacuum eternal inflation. Coupling conformal matter we calculate the Von Neu…
Entanglement Wedge Cross Section Inequalities from Replicated Geometries
Ning Bao, Aidan Chatwin-Davies, Grant N. Remmen
We generalize the constructions for the multipartite reflected entropy in order to construct spacetimes capable of representing multipartite entanglement wedge cross sections of di…
Warping Wormholes with Dust: a Metric Construction of the Python's Lunch
Ning Bao, Aidan Chatwin-Davies, Grant N. Remmen
We show how wormholes in three spacetime dimensions can be customizably warped using pressureless matter. In particular, we exhibit a large new class of solutions in (2+1)-dimensio…
