Breaking Free from the Swampland of Impossible Universes through the DESI Portal
Luis A. Anchordoqui, Dieter Lust
The persistent challenge of creating stable de Sitter vacua within string theory undermines the observational validity of the cold dark matter (CDM) model. This difficulty sug…
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…
Primordial Black Holes are 5D
Luis A. Anchordoqui, Alek Bedroya, Dieter Lüst
We revisit well-established mechanisms for primordial black hole (PBH) production, namely inflation, phase transitions, and cosmic strings, in the context of the Dark Dimension Sce…
A short overview on the Black Hole-Tower Correspondence and Species Thermodynamics
Alvaro Herráez, Dieter Lüst, Joaquin Masias +1
The breakdown of gravitational effective field theories is intimately connected to the emergence of infinite towers of light states near infinite-distance limits in field space. In…
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(Ï…
