Contribution

The authors highlight the importance of detailed methodological comparison in resolving discrepancies in EDM calculations for thallium.

Findings

The paper emphasizes the necessity of comparing basis sets and methods in EDM calculations.

It clarifies misunderstandings about previous work on thallium's EDM enhancement factor.

It argues that the recent paper did not adequately address these methodological differences.

Abstract

In a recent paper by Porsev et al. [arXiv:1201.5615v1], the authors have claimed to have resolved the controversy arising from the different ab initio results available for the EDM enhancement factor of Tl. In our opinion, any such attempt to resolve the discrepancies between different calculations has to thoroughly compare the basis sets used, methods employed and approximations considered in the two different cases. However, Porsev et al. have not succeeded in doing so in their current paper. We clarify some of their misunderstandings about our work and address some specific issues in this note.
