Simulating plasmas within the Hall-magnetohydrodynamics (Hall-MHD) regime offers a powerful framework for exploring the complex nonlinear dynamics that arise in both astrophysical environments and fusion devices. A key computational challenge stems from the Hall electric field, which introduces an additional term into Faraday’s law of induction—specifically, one proportional to ∇×((∇×BB). This term significantly impacts the evolution of the magnetic field B at small scales, between the ion and electron inertial lengths, necessitating extremely high spatial and temporal resolutions to accurately capture the underlying physics. To address these challenges, we leverage the computational efficiency and accuracy of a kinetic lattice Boltzmann approach.
