Comment on "Theoretical analysis of quantum turbulence using the Onsager ideal turbulence theory''

TL;DR

This comment critically examines a recent quantum turbulence theory, emphasizing that key physical assumptions like circulation quantization were overlooked, which may impact the validity of the proposed quantum stress cascade model.

Contribution

It highlights the omission of circulation quantization in the derivation of the quantum stress cascade in the recent theory.

Findings

Circulation quantization is a crucial physical aspect that was ignored.

The derivation of the quantum stress cascade may be incomplete without considering circulation quantization.

The critique suggests potential revisions to the quantum turbulence model.

Abstract

In a recent paper [T. Tanogami Phys. Rev. E 103, 023106 ] proposes a scenario for quantum turbulence where the energy spectrum at scales smaller than the inter-vortex distance is dominated by a quantum stress cascade, in opposition to Kelvin wave cascade predictions. The purpose of the present comment is to highlight some physical issues in the derivation of the quantum stress cascade, in particular to stress that quantization of circulation has been ignored.
