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…
Can one hear the shape of a wormhole?
Stefano Antonini, Petar Simidzija, Brian Swingle +1
A large class of flat big bang - big crunch cosmologies with negative cosmological constant are related by analytic continuation to asymptotically AdS traversable wormholes with pl…
Accelerating cosmology from a holographic wormhole
Stefano Antonini, Petar Simidzija, Brian Swingle +1
We consider cosmological models in which the cosmology is related via analytic continuation to a Euclidean asymptotically AdS planar wormhole geometry defined holographically via a…
Cosmology from the vacuum
Stefano Antonini, Petar Simidzija, Brian Swingle +1
We argue that standard tools of holography can be used to describe fully non-perturbative microscopic models of cosmology in which a period of accelerated expansion may result from…
