Quartic hilltop inflation revisited
Gabriel German
We implement a procedure by which the parameters present in the potential of Quartic Hilltop Inflation (QHI) are eliminated in favor of the scalar spectral index and the tens…
Constraining -attractor models from reheating
Gabriel German
We eliminate the parameters originally present in models of inflation of the -attractor type in favor of the scalar spectral index and the tensor-to-scalar ratio . We t…
A tunable Fabry-Pérot quantum Hall interferometer in graphene
Corentin Déprez, Louis Veyrat, Hadrien Vignaud +6
Electron interferometry with quantum Hall edge channels holds promise for probing and harnessing exotic exchange statistics of non-Abelian anyons. In semiconductor heterostructures…
Evolution of the universe during the inflationary epoch
Gabriel German
We often find in the literature solutions to the Friedmann and fluid equations for simple cosmological models during the matter, radiation or cosmological constant dominated epochs…
Measuring the expansion of the universe
Gabriel German
We draw a figure from where it is possible to measure the number of e-folds of expansion of the universe with a ruler. We find model independent bounds for the number of e-folds du…
Model independent results for the inflationary epoch and the breaking of the degeneracy of models of inflation
Gabriel German
We address the problem of determining inflationary characteristics in a model independent way. We start from a recently proposed equation which allows to accurately calculate the v…
