Distance-Higuchi Bounds on Inflationary Field Ranges and Lifetimes
Luis A. Anchordoqui, Ignatios Antoniadis, Alek Bedroya
We show that quasi-de Sitter inflation driven by a nearly flat scalar potential has a finite polynomial lifespan dictated by the interplay between the swampland Distance Conjecture…
IR Black Hole Instabilities Trigger Species-Scale Particle Production
Luis A. Anchordoqui, Alek Bedroya, Dieter Lüst +1
We propose a novel UV-IR mechanism in quantum gravity in which black hole instabilities act as a bridge to the most ultraviolet sector of the theory. Specifically, we argue that wh…
Holographic Constraints on the String Landscape
Alek Bedroya, Paul J. Steinhardt
We show that holography imposes strong and general constraints on scalar field potentials in the string landscape, determined by the asymptotic structure of the underlying spacetim…
Holography vs. Scale Separation
Alek Bedroya, Paul J. Steinhardt
In this work, we point out a contradiction between holography and scale-separated AdS (i.e. parametrically large mass gap) in string theory, making the standard assumption that the…
A species scale-driven breakdown of effective field theory in time-dependent string backgrounds
Alek Bedroya, Hayden Lee, Paul Steinhardt
We present a novel way in which effective field theory (EFT) can break down in cosmological string backgrounds depending on the behavior of the quantum gravity cutoff in infinite d…
String stars in
Alek Bedroya, David Wu
We raise a thermodynamic puzzle for Horowitz--Polchinski (HP) solutions in the presence of extra compact dimensions and show that it can be resolved by the existence of higher-dime…
