In this paper we provide a new expression for the variation of the inflaton field $\Delta\phi$ during the horizon crossing epoch in the context of single field slow roll inflationary models. Such an expression represents a generalization of the well-know Lyth bound. We also explore the consequences of a detection of permille order of the tensor-to-scalar ratio amplitude, $r$, as well as an improvement on the estimation of the scalar spectral index, $n_s$ and its running $\alpha_s$, by the…

A note on brane inflation under consistency conditions
• Physics
• 2019
To satisfy the swampland criteria, we consider the brane inflation with potential $V(\phi)=\alpha \phi^n\rm{exp}(-\beta^m \phi^m)$, which can be obtained in supergravity inflation model with a small
Energy density, temperature, and entropy dynamics in perturbative reheating
• Physics
• 2019
We discuss the perturbative decay of the energy density of a non standard inflaton field $\rho_{\phi}$ and the corresponding creation of the energy density of the relativistic fields $\rho_r$ at the

Variable inflaton equation-of-state and reheating

The Lyth Bound and the end of inflation
• Physics

We derive an extended version of the well-known Lyth Bound on the total variation of the inflaton field, incorporating higher-order corrections in slow roll. We connect the field variation Δ to both
The Lyth bound revisited

We investigate the Lyth bound relating the tensor–scalar ratio, r, to the variation of the inflaton field, Δ, over the course of inflation. For inflationary models that produce at least 55 e-folds of
Can CMB data constrain the inflationary field range
• Physics

We study to what extent the spectral index ns and the tensor-to-scalar ratio r determine the field excursion Delta phi during inflation. We analyse the possible degeneracy of Delta phi by comparing
Lyth bound of inflation with a tilt

• 2014
We provide strong evidence for universality of the inflationary field range: given an accurate measurement of (n(s), r), one can infer Delta phi in a model-independent way in the sub-Planckian regime
A field range bound for general single-field inflation

We explore the consequences of a detection of primordial tensor fluctuations for general single-field models of inflation. Using the effective theory of inflation, we propose a generalization of the

A pure gravity inflationary model for the Universe is examined which is based on adding an Epsilon term to the usual gravitational Lagrangian, and it is shown that this model gives significant inflation essentially independent of initial conditions.
Gravitational waves and large field inflation
According to the famous Lyth bound, one can confirm large field inflation by finding tensor modes with sufficiently large tensor-to-scalar ratio $r$. Here we will try to answer two related questions:

Current data from the Planck satellite and the BICEP2 telescope favor, at around the 2 σ level, negative running of the spectral index of curvature perturbations from inflation. We show that for
