Vector NLS solitons interacting with a boundary*

Cheng Zhang,Da-jun Zhang

Figure 4. Two solitons interact with the mixed Neumann (1st component) and Dirichlet (2nd component) BCs with B = − diag(1, − 1). The soliton data are: $\{{\lambda }_{j}=\tfrac{1}{2}({\mu }_{j}+{\rm{i}}{\nu }_{j}),{{\boldsymbol{b}}}_{j}\}$ and $\{{\widetilde{\lambda }}_{j}=-{\lambda }_{j},{\widetilde{{\boldsymbol{b}}}}_{j}={{\boldsymbol{b}}}_{j}\}$, j = 1, 2 with μ1 = 1, ν1 = 2, ${{\boldsymbol{b}}}_{1}^{{\rm{T}}}=(4,4)$, μ2 = 2, ν2 = 1.5, ${{\boldsymbol{b}}}_{2}^{{\rm{T}}}=(4\times {10}^{4},1\times {10}^{4})$.
