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…
TransPlanckian Censorship on Dark Dimension Inflation
Luis A. Anchordoqui, Ignatios Antoniadis, Jules Cunat
It was proposed that extra dimensions can acquire large size by higher dimensional inflation connecting two large hierarchies in particle physics and cosmology, namely the weakness…
Cosmological history after higher dimensional inflation
Luis A. Anchordoqui, Ignatios Antoniadis, Jules Cunat
It was proposed that extra dimensions can acquire large size by higher dimensional inflation connecting two large hierarchies in particle physics and cosmology, namely the weakness…
Moduli Space Quantum Mechanics
Luis Anchordoqui, Muldrow Etheredge, Dieter Lust
In this paper, continuing the discussion about Species Quantum Mechanics, we investigate quantum mechanics in moduli spaces using a mini-superspace approach. From this perspective,…
Species Quantum Mechanics
Luis A. Anchordoqui, Dieter Lust, Severin Lüst
In this note we introduce some concepts of Species Quantum Mechanics. Specifically, we consider quantum operators that correspond to the species number and the tower mass sca…
Bulk/boundary Modular Quintessence and DESI
Luis A. Anchordoqui, Ignatios Antoniadis, Niccolò Cribiori +4
The latest DESI DR2 results, when combined with other independent cosmological data on the Cosmic Microwave Background and supernovas, suggest a preference for dynamical dark energ…
S-dual Quintessence, the Swampland, and the DESI DR2 Results
Luis A. Anchordoqui, Ignatios Antoniadis, Dieter Lust
We propose a dark energy model in which a quintessence field rolls near the vicinity of a local maximum of its potential characterized by the simplest self-dual form $V(ϕ)…
Two Micron-Size Dark Dimensions
Luis Anchordoqui, Ignatios Antoniadis, Dieter Lust
Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In our paper we examine various observational bounds in scenarios w…
Thin-wall vacuum decay in the presence of a compact dimension meets the and tensions
Luis A. Anchordoqui, Ignatios Antoniadis, Daniele Bielli +2
The proposal of a rapid sign-switching cosmological constant in the late universe, mirroring a transition from anti-de Sitter (AdS) to de Sitter (dS) space, has significantly impro…
Bulk Black Hole Dark Matter
Luis A. Anchordoqui, Ignatios Antoniadis, Dieter Lust +1
The dark dimension provides a mechanism to resolve the cosmological hierarchy problem and assembles a colosseum for dark matter contenders. In a series of recent publications we in…
Landscape, Swampland, and Extra Dimensions
Luis Anchordoqui, Ignatios Antoniadis, Dieter Lust
By combining swampland conjectures with observational data, it was recently suggested that the cosmological hierarchy problem (i.e. the smallness of the dark energy in Planck units…
More on Black Holes Perceiving the Dark Dimension
Luis A. Anchordoqui, Ignatios Antoniadis, Dieter Lust
In the last two years the dark dimension scenario has emerged as focal point of many research interests. In particular, it functions as a stepping stone to address the cosmological…
The Dark Dimension, the Swampland, and the Dark Matter Fraction Composed of Primordial Near-Extremal Black Holes
Luis A. Anchordoqui, Ignatios Antoniadis, Dieter Lust
In a recent publication we studied the decay rate of primordial black holes perceiving the dark dimension, an innovative five-dimensional (5D) scenario that has a compact space wit…
Anti-de Sitter de Sitter transition driven by Casimir forces and mitigating tensions in cosmological parameters
Luis A. Anchordoqui, Ignatios Antoniadis, Dieter Lust
Over the last few years, low- and high-redshift observations set off tensions in the measurement of the present-day expansion rate and in the determination of the amplitude o…
