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…

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…

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…
