(a), (b) and (c): The evolution of stable symmetric bound states in the model with the SDF sign of the nonlinearity, as produced by simulations of Eq. (6) with \(\sigma =-1\) and parameters \(( \varepsilon ,k)=(2,1.5)\), (2, 2) and (5, 8), respectively. (d, e) and (f): The evolution of moderately and weakly unstable antisymmetric bound states for \((\varepsilon ,k)=(2,1)\), (2, 1.5), and (5, 8), respectively. (g), (h) and (i): The evolution of stable bound states with moderately, weakly, and strongly broken antisymmetry, for \((\varepsilon ,k)=(2,1.5)\), (2.8, 1.8) and (5, 8), respectively.
