Erratum: Nonlinear spherical perturbations in quintessence models of dark energy

TL;DR

This erratum corrects previous results on nonlinear spherical perturbations in quintessence dark energy models, showing that earlier amplitude estimates were inflated due to a coding error, and that dark energy perturbations are actually much smaller.

Contribution

The paper provides corrected analysis of dark energy perturbations in quintessence models, clarifying previous overestimations caused by a numerical scaling error.

Findings

Dark matter perturbations remain unchanged after correction.

Dark energy perturbations are significantly smaller than previously reported.

Spatial variations in the equation of state are also reduced.

Abstract

We reported results of our study on non-linear spherical perturbations in quintessence models of dark energy. In the process of some follow up studies we discovered that a scaling factor in the code used for numerical calculations that should have been set to unity was set to a large value. Thus the scale of perturbations was much larger than intended, and for the larger scales the amplitude of dark matter perturbations was much higher than realistic. We provide corrected results here in this erratum. We find that there is no change in the perturbations for dark matter. The amplitude of perturbations in dark energy is much smaller than presented in the paper. Same holds true for spatial variation in the equation of state parameter.
