This generalization consists of including appropriate couplings between Lorentz scalar and pseudoscalar fields with EM fields in the Lagrangian of the system. We exactly solve two single-particle problems: first, a Hydrogen-like system; second, a relativistic Schrödinger-like equation for a linear confining potential. We comment on the relevance of this approach to explore fermion (e.g. neutron) self-interactions as solitonic models of the neutron.</p>info:eu-repo/semantics/restrictedAccessDirac-Pauli equationneutron interactions with EM fieldsneutron solitonsnonlinear Dirac equationArticle
