Spinodal Instabilities and Super-Planckian Excursions in Natural Inflation
Andreas Albrecht, R. Holman, Benoit J. Richard
Models such as Natural Inflation that use Pseudo-Nambu-Goldstone bosons (PNGB's) as the inflaton are attractive for many reasons. However, they typically require trans-Planckian fi…
Holographic bounds and finite inflation
Daniel Phillips, Andrew Scacco, Andreas Albrecht
We compare two holographic arguments that impose especially strong bounds on the amount of inflation. One comes from the de Sitter Equilibrium cosmology and the other from the work…
Cosmological Consequences of Initial State Entanglement
Andreas Albrecht, Nadia Bolis, R. Holman
We explore the cosmological consequences of having the fluctuations of the inflaton field entangled with those of another scalar, within the context of a toy model consisting of no…
No Firewalls or Information Problem for Black Holes Entangled with Large Systems
Henry Stoltenberg, Andreas Albrecht
We discuss how under certain conditions the black hole information puzzle and the (related) arguments that firewalls are a typical feature of black holes can break down. We first r…
Eternal Inflation with Arrival Terminals
Henry Stoltenberg, Andreas Albrecht
We analyze the cosmological role of terminal vacua in the string theory landscape, and point out that existing work on this topic makes very strong assumptions about the properties…
Testing quantum gravity by nanodiamond interferometry with nitrogen-vacancy centers
Andreas Albrecht, Alex Retzker, Martin B. Plenio
Interferometry with massive particles may have the potential to explore the limitations of standard quantum mechanics in particular where it concerns its boundary with general rela…
