Multifield dark energy: Interplay between curved field space and curved spacetime
Diego Gallego, J. Bayron Orjuela-Quintana
Exponential quintessence models motivated by string compactifications naturally involve both a dilatonic scalar and its axionic partner evolving on a curved field space, while spat…
Anisotropic Dark Energy from String Compactifications
Diego Gallego, J. Bayron Orjuela-Quintana, César A. Valenzuela-Toledo
We explore the cosmological dynamics of a minimalistic yet generic string-inspired model for multifield dark energy. Adopting a supergravity four-dimensional viewpoint, we motivate…
Finite temperature effects in modular cosmology
Diego Gallego
We revisit the cosmological history in the presence of light moduli by including possible thermal effects in the scalar potential. The well known cosmological moduli problem regard…
A New Class of de Sitter Vacua in Type IIB Large Volume Compactifications
Diego Gallego, M. C. David Marsh, Bert Vercnocke +1
We construct a new class of metastable de Sitter vacua of flux compactifications of type IIB string theory. These solutions provide a natural extension of the `Large Volume Scenari…
On the Effective Description of Large Volume Compactifications
Diego Gallego
We study the reliability of the Two-Step moduli stabilization in the type-IIB Large Volume Scenarios with matter and gauge interactions. The general analysis is based on a family o…
Moduli Stabilization in non-Supersymmetric Minkowski Vacua with Anomalous U(1) Symmetry
Diego Gallego, Marco Serone
We study how two moduli can be stabilized in a Minkowski/de Sitter vacuum for a wide class of string-inspired Supergravity models with an effective Fayet-like Supersymmetry breakin…
