Speed-of-light pulses in the massless nonlinear Dirac equation with a potential

Niurka R. Quintero, Franz G. Mertens, Fred Cooper +2

We consider the massless nonlinear Dirac (NLD) equation in $1+1$ dimension with scalar-scalar self-interaction $\frac{g^2}{2}(\bar{\Psi }\Psi {)}^2$ in the presence of three external electro…
