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…
