a, b \({\bar{I}}_{1}\) and (c, d) \({\bar{J}}_{1}\) for the \({{{{\boldsymbol{r}}}}}_{1}^{{{{\rm{L}}}}}=({x}_{1}^{{{{\rm{L}}}}},{y}_{1}^{{{{\rm{L}}}}})\) space at (a, c) \(({V}_{0}^{{{{\rm{L}}}}},{V}_{1}^{{{{\rm{L}}}}})=(+1,+1)\) and (b, d) \(({V}_{0}^{{{{\rm{L}}}}},{V}_{1}^{{{{\rm{L}}}}})=(+1,-1)\). The color bars indicate the amplitude of (a, c) \({\bar{I}}_{1}({{{{\boldsymbol{r}}}}}_{0}^{{{{\rm{L}}}}})\) and (b, d) \({\bar{J}}_{1}({{{{\boldsymbol{r}}}}}_{0}^{{{{\rm{L}}}}})\). We set the core positions as \(({x}_{0}^{{{{\rm{L}}}}},{y}_{0}^{{{{\rm{L}}}}})=(-30a,0.5a)\) and the vortex size as \({z}_{1}^{{{{\rm{L}}}}}=10a\) (\({N}_{x}^{{{{\rm{L}}}}}={N}_{x}^{{{{\rm{R}}}}}=45\) and Ny = 30). The Gray line indicates the scanning site in Fig. 4.
