Inflationary Particle Production and the Swampland
Dieter Lüst, Joaquin Masias, Mauro Pieroni +1
We investigate the impact of particle production during inflation in scenarios where an infinite tower of states features a mass scale that decreases exponentially along the inflat…
Quintessential -attractors fit DESI
Alessandro Borys, Joaquin Masias, Marco Scalisi
We study quintessence in -attractor models in light of recent DESI indications for dynamical dark energy. We show that the \emph{knee} of the attractor potential provides an ex…
Higher Curvature Inflation and the Species Scale
Joaquin Masias
We study the scalar potentials that arise from higher curvature corrections in general theories of gravity and their connection to a dynamical species scale. Starting from g…
Dark bubble cosmology and the equivalence principle
Ivano Basile, Alessandro Borys, Joaquin Masias
The main goal of string phenomenology is to find realistic models of particle physics and cosmology within string theory. Dark bubble cosmology is an alternative to string compacti…
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…
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…
