Recent studies of the thermodynamic phase diagrams of the Gross-Neveu model (GN2), and its chiral cousin, the NJL2 model, have shown that there are phases with inhomogeneous crystalline condensates. ...

In this paper, we investigate some properties of the multi-symplectic Runge-Kutta (MSRK) methods for nonlinear Dirac equations in relativistic quantum physics. It is showed that the symplectic Runge-K...
