The dual role of shear in large-scale dynamos
Axel Brandenburg
The role of shear in alleviating catastrophic quenching by shedding small-scale magnetic helicity through fluxes along contours of constant shear is discussed. The level of quenchi…
A growing dynamo from a saturated Roberts flow dynamo
Andreas Tilgner, Axel Brandenburg
Using direct simulations, weakly nonlinear theory and nonlinear mean-field theory, it is shown that the quenched velocity field of a saturated nonlinear dynamo can itself act as a…
Nonlinear magnetic diffusivity and alpha tensors in helical turbulence
A. Brandenburg, K. -H. Rädler, M. Rheinhardt +1
The effect of a dynamo-generated mean magnetic field of Beltrami type on the mean electromotive force is studied. In the absence of the mean magnetic field the turbulence is assume…
Decomposition of Complex Reaction Networks into Reactons
Raphaël Plasson, Hugues Bersini, Axel Brandenburg
The analysis of complex reaction networks is of great importance in several chemical and biochemical fields (interstellar chemistry, prebiotic chemistry, reaction mechanism, etc).…
Modeling a Maunder Minimum
A. Brandenburg, E. A. Spiegel
We introduce on/off intermittency into a mean field dynamo model by imposing stochastic fluctuations in either the alpha effect or through the inclusion of a fluctuating electromot…
