In the Gross–Neveu model, consider static soliton multiplets other than the DHN multiplets with $K=1$, $q=0$, the CCGZ kink multiplet with $K=1$, $|q|=1$, and the heavier topologic…

Let a Gross–Neveu soliton be simulated by the Fourier split-step method with time step $\Delta t$ and spatial step $\Delta x$. Let $k_{n\pi}$-peaks denote the relevant peaks in the…
