The simplest α-attractor T model is given by the potential V = V0 tanh (λφ/Mpl). However its generalization to the class of models of the type V = V0 tanh (λφ/Mpl) is difficult to interpret as a model of inflation for most values of p. Keeping the basic model, we propose a new generalization, where the final potential is of the form V = V0(1 − sech(λφ/Mpl)), which does not present any of the problems that plague the original generalization, allowing a successful interpretation as a model of…

Constraining $\alpha$-attractor models from reheating
TLDR
This work eliminates the parameters originally present in models of inflation of the α-attractor type and finds that the tensor-to-scalar ratio r (and as a consequence the energy scale of inflation) is bounded from below.
A Natural Inflation inspired model
We propose a modification of the Natural Inflation (NI) potential in such a way that the spontaneous symmetry breaking scale f can take values less than one (in Planck units). The proposed potential

We carry out a fully analytical study of the phenomenology of α-attractor T-models defined by the potential V = V0tanhp(λϕ/M_pl). We obtain expressions for the number of e-folds during inflation Nke
Non-slow-roll dynamics in α-attractors
In this paper we consider the α−attractor model and study inflation under a non-slow-roll dynamics. More precisely, we follow the approach recently proposed by Gong and Sasaki [1] by means of
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
Unity of cosmological inflation attractors.
TLDR
The aim of this Letter is to elucidate the common denominator of these attractors: their robust predictions stem from a joint pole of order 2 in the kinetic term of the inflaton field in the Einstein frame formulation prior to switching to the canonical variables.
Large field inflation and double α-attractors
A bstractWe consider a broad class of inflationary models that arise naturally in super-gravity. They are defined in terms of a parameter α that determines the curvature and cutoff of these models.
The double attractor behavior of induced inflation
A bstractWe describe an induced inflation, which refers to a class of inflationary models with a generalized non-minimal coupling ξg(ϕ)R and a specific scalar potential. The defining property of
Instant preheating in quintessential inflation with α-attractors
We investigate a compelling model of quintessential inflation in the context of α-attractors, which naturally result in a scalar potential featuring two flat regions; the inflationary plateau and the
α-Attractors and reheating in a nonminimal inflationary model
We study [Formula: see text]-attractor models with both E-model and T-model potential in an extended Nonminimal Derivative (NMD) inflation where a canonical scalar field and its derivatives are
Constraints on α -attractor inflation and reheating
We investigate a constraint on reheating followed by �-attractor-type inflation (the E-model and T-model) from an observation of the spectral index ns. When the energy density of the universe is
Non-minimal Inflationary Attractors
Recently we identified a new class of (super)conformally invariant theories which allow inflation even if the scalar potential is very steep in terms of the original conformal variables.
