Vector NLS solitons interacting with a boundary*

Cheng Zhang,Da-jun Zhang

Figure 3. Three stationary solitons interfere with themselves at the boundary subject to the Robin BCs (α = 2). Here, ${{\boldsymbol{\beta }}}^{{\rm{T}}}=\left(\tfrac{4}{\sqrt{65}},\tfrac{7}{\sqrt{65}}\right);$ ${\lambda }_{1}={\rm{i}}\tfrac{6}{2}$, ${{\boldsymbol{b}}}_{1}=\tfrac{{\boldsymbol{\beta }}}{\sqrt{5}};$ ${\lambda }_{2}={\rm{i}}\tfrac{5}{2}$, ${{\boldsymbol{b}}}_{2}=\tfrac{{\boldsymbol{\beta }}}{\sqrt{9}};$ ${\lambda }_{3}={\rm{i}}\tfrac{7}{2}$, ${{\boldsymbol{b}}}_{3}=\tfrac{{\boldsymbol{\beta }}\sqrt{3}}{\sqrt{11}}$.
