Contribution

It introduces the idea that multiscaling universality in 3D MHD turbulence can vary continuously with certain parameters, a novel concept in turbulence theory.

Findings

Dependence of dimensionless constants on correlation symmetries

Proposal of multiscaling universality class variation

Discussion of experimental and theoretical implications

Abstract

We analyse the universal properties of nonequilibrium steady states of driven Magnetohydrodynamic (MHD) turbulence in three dimensions (3d). We elucidate the dependence of various phenomenologically important dimensionless constants on the symmetries of the two-point correlation functions. We, for the first time, also suggest the intriguing possibility of multiscaling universality class varying continuously with certain dimensionless parameters. The experimental and theoretical implications of our results are discussed.
