Stability of solitary waves in the nonlinear Dirac equation with arbitrary nonlinearity

Sihong Shao, Niurka R. Quintero, Franz G. Mertens +3

We consider the nonlinear Dirac equation in 1+1 dimension with scalar-scalar self interaction $\frac{g^2}{\kappa +1}(\bar{\Psi }\Psi {)}^{\kappa +1}$ and with mass $m$. Using the exact analytic form…
