Semiclassical Self Consistent Treatment of the Emergence of Seeds of Cosmic Structure. The second order construction
Pedro Cañate, Erandy Ramirez, Daniel Sudarsky
In this work we extend the results of [1] where, Semiclassical Selfconsistent Configurations (SSC) formalism was introduced. The scheme combines quantum field theory on a backgroun…
Generic inference of inflation models by local non-Gaussianity
Sebastian Dorn, Erandy Ramirez, Kerstin E. Kunze +2
The presence of multiple fields during inflation might seed a detectable amount of non-Gaussianity in the curvature perturbations, which in turn becomes observable in present data…
Generic inference of inflation models by non-Gaussianity and primordial power spectrum reconstruction
Sebastian Dorn, Erandy Ramirez, Kerstin E. Kunze +2
We present a generic inference method for inflation models from observational data by the usage of higher-order statistics of the curvature perturbation on uniform density hypersur…
Low power on large scales in just enough inflation models
Erandy Ramirez
An early stage of kinetic energy domination for inflation is applied to single-field quadratic and hybrid-type potentials considering only the amount of inflation necessary to solv…
Predictions of just-enough inflation
Erandy Ramirez, Dominik J. Schwarz
We find the best-fit cosmological parameters for a scenario of inflation with only the sufficient amount of accelerated expansion for the potential. While for the simplest s…
Just enough inflation
Dominik J. Schwarz, Erandy Ramirez
We propose a version of chaotic inflation, in which a fundamental scale M, well below the Planck scale M_P, fixes the initial value of the effective potential. If this scale happen…
