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…
Effective upliftings in Large volume compactifications
Diego Gallego
After reviewing several mechanisms proposed to get a dS/Minkowski vacuum in moduli stabilization scenarios of type-IIB superstring orientifold compactifications we propose a criter…
Light field integration in SUGRA theories
Diego Gallego
We revisit the integration of fields in N=1 Supergravity with the requirement that the effective theory has a reliable two-derivative supersymmetric description. In particular we s…
