We investigate the planar nonlinear quantum dynamics of a self-interacting electron in the presence of an external homogeneous magnetic field in flat space-time dimensions. In cylindrical coordinates, nonlinearities are introduced via the Nambu–Jona-Lasinio interaction. Special attention is given to the strong-field QED regime. We obtain the approximate (nonlinear) ground-state Landau energy levels together with their respective eigenfunctions. We briefly comment on the relevance of this model to elucidate certain processes thought to occur near the surfaces of neutron stars.
