Alice in Warpland: KK modes, Warped Compactifications and the Swampland
Salvatore Raucci, Ignacio Ruiz, Irene Valenzuela
We investigate the asymptotic behavior of Kaluza-Klein (KK) towers in warped compactifications to Minkowski space. Focusing on the overall decompactification limit, we derive the s…
Cosmology of light towers and swampland constraints
Gonzalo F. Casas, Ignacio Ruiz
We study the dynamical evolution of FLRW cosmologies in the presence of a tower of scalar light states and a runaway exponential potential. Some of the attractor solutions have pro…
Cosmological Chameleons, String Theory and the Swampland
Gonzalo F. Casas, Miguel Montero, Ignacio Ruiz
We study a scenario with a transient phase of cosmological acceleration that could potentially be realized in asymptotic corners of String Theory moduli space. A very steep scalar…
To curve, or not to curve: Is curvature-assisted quintessence observationally viable?
George Alestas, Matilda Delgado, Ignacio Ruiz +3
Single-field models of accelerated expansion with nearly flat potentials, despite being able to provide observationally viable explanations for the early-time cosmic inflation and…
