While the plasmoid instability is well characterized in 2D fully ionized plasmas, its behavior in the presence of neutral-dominated plasma remains poorly understood in the nonlinear, high-Lundquist-number ($S = 10^5$) regime. We present high-resolution ($16384 \\times 4096$ cells) two-dimensional two-fluid (ion $+$ neutral) simulations of Harris-sheet reconnection with upstream plasma beta $\\beta = 2$, comparing fully ionized and partially ionized (ionization fraction $\\xi = 10^{-1}$ and $10^{-2}$) re","authors_text":"Alex Lazarian, Grzegorz Kowal, Hui Li, James M.
