Computational simulation demonstrates kinetic tearing mode dynamics in cylindrical plasmas, highlighting consistency with reduced magnetohydrodynamic theory.
Particle-in-cell simulations of (m=2,n=1) tearing mode in cylindrical plasmas are carried out with kinetic electrons using the split-weight control-variate algorithm [Y. Chen and S. E. Parker, J. Comput. Phys. 220, 839 (2007)]. Radially, global simulation shows global mode structure in agreement with reduced-magnetohydrodynamic eigenmode calculation. Simulations of the tearing layer are verified with analytic results for the collisionless, semi-collisional, and drift-tearing mode.
