説明

<jats:p>Analytic theory has yielded contradictory predictions regarding the stabilizing role of electron dynamics on the collisionless tearing instability in a field‐reversal region with finite normal magnetic field component <jats:italic>B<jats:sub>z</jats:sub></jats:italic>. Two‐dimensional (<jats:italic>x, z</jats:italic>) simulations in which both electrons and ions are treated as particles demonstrate that, for the case of thin current sheets (<jats:italic>R<jats:sub>i</jats:sub></jats:italic>/ λ ∼ 1, where <jats:italic>R<jats:sub>i</jats:sub></jats:italic> is the ion Larmor radius based on the lobe field and λ is the current sheet half thickness) and with weakly chaotic electron orbits, the ion tearing mode is indeed stabilized under the mild condition that k<jats:italic>ρ</jats:italic><jats:sub>e</jats:sub> ≲ 1, where <jats:italic>ρ</jats:italic><jats:sub>e</jats:sub> is the electron Larmor radius in the <jats:italic>B<jats:sub>z</jats:sub></jats:italic> field.</jats:p>
