Comment on "Superfluid turbulence from quantum Kelvin wave to classical Kolmogorov cascades" [arXiv:0905.0159] by J. Yepez, G. Vahala, L.Vahala and M. Soe

TL;DR

This paper critiques the interpretations of Kelvin wave and Kolmogorov turbulence in a previous study, emphasizing the need for more theoretical analysis to accurately understand the numerical results.

Contribution

It provides a critical commentary on prior work, highlighting the misleading aspects and proposing a direction for further theoretical investigation.

Findings

Previous interpretations are misleading

More theoretical analysis is necessary

A new approach to interpret numerical results is suggested

Abstract

Both the Kelvin wave and the Kolmogorov turbulence interpretations presented in the PRL, [v. 103, 084501 (2009) by J. Yepez, G. Vahala, L.Vahala and M. Soe, arXiv:0905.0159] are misleading, and much more theoretical analysis needs to be done for the interpretation of the important numerical results obtained by the authors. A way to do this is suggested.
