Charged particle transport across magnetic field driven by magnetosonic solitons in plasma

This work investigates the unidirectional transport of charged particles across magnetic field lines driven by magnetosonic solitons in a collisionless plasma. Within the framework of a magnetohydrodynamic model, numerical solutions as well as analytical expressions for small-amplitude solitons are obtained, and it is shown that particles experience a unidirectional displacement proportional to the square root of the wave amplitude, indicating that solitons generate substantial matter transport across the magnetic field.
