A LooKK at the Higuchi Bound
Dieter Lüst, Joaquin Masias
Massive spin 2 fields on de Sitter must satisfy the Higuchi bound, . Compactifications of higher dimensional gravity to come with a tower of Kaluza-Kl…
Black Hole-Tower Correspondence: Species backreaction in minimal black hole limits
Miquel Aparici, Alvaro Herráez, Joaquin Masias
The Black Hole-String Correspondence identifies the microstates of a minimal black hole with those of a highly excited string. In decompactification limits, where the light states…
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 exc…
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…
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…
Dynamical dark energy in 0'B braneworlds
Ivano Basile, Alessandro Borys, Joaquin Masias
We build a novel realization of dark bubble cosmology in non-supersymmetric string theory. Among the simplest models in ten dimensions, the type 0'B orientifold is the unique optio…
On the Origin of Species Thermodynamics and the Black Hole - Tower Correspondence
Alvaro Herráez, Dieter Lüst, Joaquin Masias +1
Species thermodynamics has been proposed in analogy to black hole thermodynamics. The entropy scales like an area and is given by the mere counting of the number of the species. In…
Starobinsky Inflation in the Swampland
Dieter Lust, Joaquin Masias, Benjamin Muntz +1
We argue that the Starobinsky model of inflation, realised via an term in the Lagrangian, can originate from quantum effects due to a tower of light species. By means of two…
