Single-field models of $\alpha$-attractor quintessential inflation provide a unified picture of the two periods of early- and late-time cosmic acceleration, where both inflation and dark energy are described by a single scalar degree of freedom rolling down a runaway potential. These theoretically well-motivated models have distinct observational predictions that are in agreement with existing cosmological data. We show that the next generation of large-scale structure surveys, even when no… 


α-attractor dark energy in view of next-generation cosmological surveys
The α-attractor inflationary models are nowadays favored by CMB Planck observations. Their similarity with canonical quintessence models motivates the exploration of a common framework that explains
Observational constraints on successful model of quintessential Inflation
We study quintessential inflation using a generalized exponential potential V(ϕ)∝ exp (−λ ϕn/MPln), n>1, the model admits slow-roll inflation at early times and leads to close-to-scaling behaviour in
$\alpha $-Attractors: Planck, LHC and Dark Energy
We develop four-parameter supergravity models of inflation and dark energy, constrained so that ${\delta\rho\over \rho}$, $n_s$ and the cosmological constant $\Lambda $ take their known observable
Higgs-dilaton cosmology: An inflation-dark-energy connection and forecasts for future galaxy surveys
The Higgs-Dilaton model is a scale-invariant extension of the Standard Model non-minimally coupled to gravity and containing just one additional degree of freedom on top of the Standard Model
α-attractors: Planck, LHC and dark energy
A bstractWe develop four-parameter supergravity models of inflation and dark energy, constrained so that δρρ$$ \frac{\delta \rho }{\rho } $$, ns and the cosmological constant Λ take their known
Dark energy, α-attractors, and large-scale structure surveys
Over the last few years, a large family of cosmological attractor models has been discovered, which can successfully match the latest inflation-related observational data. Many of these models can
Unified framework for early dark energy from α -attractors
One of the most appealing approaches to ease the Hubble tension is the inclusion of an early dark energy (EDE) component that adds energy to the Universe in a narrow redshift window around the time
Bayesian evidence for α-attractor dark energy models
Dark energy models with tracker properties have gained attention due to the large range of initial conditions leading to the current value of the dark energy density parameter. A well-motivated
Quintessence: a review
Quintessence is a canonical scalar field introduced to explain the late-time cosmic acceleration. The cosmological dynamics of quintessence is reviewed, paying particular attention to the evolution
Quintessential inflation with α-attractors
A novel approach to quintessential inflation model building is studied, within the framework of α-attractors, motivated by supergravity theories. Inflationary observables are in excellent agreement
