Generalization of the Guendelman nonlinear electrodynamics model

Abstract

Abstract In this study, we present a generalized version of the specific nonlinear electrodynamic model introduced by Guendelman [PLB640(2006)201] as a result of spontaneously breaking the scale invariance of Maxwell’s linear theory. The generalized model involves a new integer parameter n so that n = 2 reproduces Guendelman’s model. Although with each n in principle there exist a new model but technically only n = 2 and n = 3 yield a closed analytical expression.
