Effect of Hyper-Resistivity on Nonlinear Tearing Modes
Abstract
We analytically explore nonlinear tearing modes with the anomalous electron viscosity or, as it is normally called, hyper-resistivity. In contrast to the flux average method used by previous work, we employ the standard singular perturbation technique and a quasilinear method to obtain the time evolution equation of tearing modes. The finding that the magnetic flux grows with time in a scaling as t 2/3 demonstrates that nonlinear tearing modes with the hyper-resistivity effect alone have a weaker dependence on time than that of the corresponding resistive case.
