Comment on "Reappraisal of the Electric Dipole Moment Enhancement Factor for Thallium"

TL;DR

This paper critiques a recent calculation of the Thallium EDM enhancement factor, arguing that the claim of increased accuracy is unsubstantiated and clarifying previous methods in response to recent comments.

Contribution

It provides a critical analysis of recent claims about EDM calculations for Thallium and clarifies the authors' original methodology.

Findings

The recent claim of highest accuracy is not sufficiently supported.

The authors' original calculation method is clarified and defended.

Misleading comments about previous work are addressed.

Abstract

Recent paper by Nataraj {\em et al} (Phys. Rev. Lett. {\bf 106}, 200403 (2011)) presents calculations of the EDM enhancement factor for Tl, which disagrees with previous most accurate calculations. The authors claim that their calculations of Tl EDM are the most accurate due to more complete treatment of higher-order correlations. In this note we argue that this claim is not supported by sufficient evidence. Nataraj {\em et al} also present misleading comments about our calculations. We explain our method and reply to the Nataraj {\em et al} comments.
