 The spontaneous symmetry breaking reported in a turbulent swirling flow at v equals 40,000 by quartet at all, 2010 P-H-Y-S Rev. Let. 105214501 can be described through a continuous one-parameter family transformation, amounting to a phase shift of steady states, and the associated susceptibility diverges at the transition in a way similar to what is observed in the experimental results, meaning that the zero-mode mechanism is a good candidate to explain the experimental symmetry breaking. This article was offered by B. Sainte-Michel, F. Davio, and B. Jubrule.
