Nonlinear Transformation for a Class of Gauged Schroedinger Equations with Complex Nonlinearities

Abstract

In the present contribution we consider a class of Schroedinger equations containing complex nonlinearities, describing systems with conserved norm $|\psi {|}^2$ and minimally coupled to an abelian gauge field. We introduce a nonlinear transformation which permits the linearization of the source term in the evolution equations for the gauge field, and transforms the nonlinear Schroedinger equations in another one with real nonlinearities. We show that this transformation can be performed either on the gauge field $A_{\mu }$ or, equivalently, on the matter field $\psi$. Since the transformation does not change the quantities $|\psi {|}^2$ and $F_{\mu \nu }$, it can be considered a generalization of the gauge transformation of third kind introduced some years ago by other authors.
