Algebraic nonlinear growth of the resistive kink instability
From a simple model, it is shown that the resistive kink mode grows algebraically, with W proportional to the square of t, for island size W exceeding the resistive layer width. The model only uses the properties of the linear eigenfunction and of current-sheet reconnection. Because of the geometry of the inflow velocity, the usual quasisingular behaviour in the current sheet edge region vanishes. The theory is in quantitative agreement with high-S number numerical simulations.
