Non-vanishing pseudo-scalars in turbulence may give rise to an effective suppression of enhanced transports due to turbulence. In the context of dynamo, the turbulent cross helicity (velocity–magnetic-field correlation in fluctuations) as well as the turbulent kinetic and/or current helicty, leads to effective suppression of the turbulent magnetic diffusivity. This is because, in...
