The interaction of turbulence, magnetic islands and zonal fields in fluid plasma models with cubic non-linearities
Daniele Villa, Nicolas Dubuit, Olivier Agullo +1
It is shown that magnetic islands generated by pressure-gradient-driven turbulence are common across a wide range of conditions. The interaction among turbulence, magnetic island a…

Zonal fields as catalysts and inhibitors of turbulence-driven magnetic islands
Daniele Villa, Nicolas Dubuit, Olivier Agullo +1
A novel coalescence process is shown to take place in plasma fluid simulations, leading to the formation of large-scale magnetic islands that become dynamically important in the sy…
