Wave packet density \(\pmb{\rho= |\psi_{1}|^{2} + |\psi_{2}|^{2} + |\psi_{3}|^{2} + |\psi_{4}|^{2}}\) for the scheme solving Dirac equation with NJL interaction. These snapshots are taken at time \(t=200\) for \(k=0.004\), 0.04 and 0.4 (from top to bottom). The figure shows how the initial energy affects the separation phenomenon. In particular, at low energy, \(k=0.004\), no splitting of the wavepackest is observed.
