From Inflation to Quintessence: a History of the Universe in String Theory
Michele Cicoli, Francesc Cunillera, Antonio Padilla +1
We present a type IIB 4D string model with stabilised moduli which is able to describe the history of the universe from inflation to quintessence. The underlying Calabi-Yau volume…
Dark energy: EFTs and supergravity
Francesc Cunillera
The subject of this thesis is cosmological implications of string compactifications understood in a broad sense. In the first half of the thesis, we will begin by reviewing the fou…
CMB constraints on monodromy inflation at strong coupling
Edmund J. Copeland, Francesc Cunillera, Adam Moss +1
We carry out a thorough numerical examination of field theory monodromy inflation at strong coupling. We perform an MCMC analysis using a Gaussian likelihood, fitting multiparamete…
Quintessence and the Swampland: The numerically controlled regime of moduli space
Michele Cicoli, Francesc Cunillera, Antonio Padilla +1
We provide a detailed discussion of the main theoretical and phenomenological challenges of quintessence model building in any numerically controlled regime of the moduli space of…
Quintessence and the Swampland: The parametrically controlled regime of moduli space
Michele Cicoli, Francesc Cunillera, Antonio Padilla +1
We provide evidence that slow roll is not possible in any parametrically controlled regime of the moduli space of string theory. This is proven in full generality in the asymptotic…
Quadratic curvature corrections to stringy effective actions and the absence of de Sitter vacua
Francesc Cunillera, William T. Emond, Antoine Lehébel +1
We investigate the combined effect of fluxes and higher-order curvature corrections, in the form of the Gauss-Bonnet term, on the existence of de Sitter vacua in a heterotic string…
A stringy perspective on the coincidence problem
Francesc Cunillera, Antonio Padilla
We argue that, for generic string compactifications, dark energy is likely to signal the beginning of the end of our universe, perhaps even through decompactification, with possibl…
A natural theory of dark energy
Lorenzo Bordin, Francesc Cunillera, Antoine Lehébel +1
We propose a mechanism that generates a naturally light dark energy field (with Hubble scale mass), starting from a theory with exclusively high scale (Planckian) couplings. It is…
The Gross-Pitaevskii equations of a static and spherically symmetric condensate of gravitons
Francesc Cunillera, Cristiano Germani
In this paper we consider the Dvali and Gómez assumption that the end state of a gravitational collapse is a Bose-Einstein condensate of gravitons. We then construct the two Gross-…
