对“T = 0超流体turbulence中开尔文波动力学和开尔文波级联的对称性“的评论[ arXiv:1201.3188]

Comment on "Symmetry of Kelvin-wave dynamics and the Kelvin-wave cascade in the T = 0 superfluid turbulence" [arXiv:1201.3188]

Victor S. L'vov, Sergey V. Nazarenko

摘要:

本文对E. B. Sonin,PRB v 85,104516(2012)[arXiv:1201.3188],我们发现自己严重不同意。我们用这个选项来阐明开尔文波湍流理论的一些重要问题,在E。B. Sonin的论文,特别是,在强的Vinen谱和L 'vov-Nazarenko谱的弱湍流的开尔文波之间的关系。我们还讨论了我们的明确计算的开尔文波相互作用的哈密顿量和“对称性参数”,应该解决之间的矛盾的Kozik-Svistunov和L 'vov-Nazarenko谱的弱湍流的开尔文波的作用。

英文摘要:

We comment on the paper by E. B. Sonin, PRB v 85, 104516 (2012) [arXiv:1201.3188], with which we find ourselves in serious disagreement. We use this option to shed light on some important issues of a theory of Kelvin wave turbulence, touched in E. B. Sonin's paper, in particular, on the relation between the Vinen spectrum of strong- and the L'vov-Nazarenko spectrum of weak-turbulence of Kelvin waves. We also discuss the role of our explicit calculation of the Kelvin wave interaction Hamiltonian and of the "symmetry arguments" that are supposed to resolve a contradiction between the Kozik-Svistunov and L'vov-Nazarenko spectrum of weak turbulence of Kelvin waves.
