Nonlinear Dirac equations that preserve the conformal degree [PDF]
A. D. AlhaidariMaintaining the conformal degree of the spinor field in D+1 space-time and choosing dimensionless coupling, we obtain the nonlinear self-interaction term in the spinor Lagrangian from which the Dirac equation is derived by variations. In 1+1 dimension, we show that these requirements result in the "conventional" quartic form of the nonlinear interaction and we present the corresponding general equation.View original: http://arxiv.org/abs/1212.6000
