Figure 2. The profiles of ${ \mathcal P }{ \mathcal T }$-symmetric QDs in ${ \mathcal P }{ \mathcal T }$-symmetric optical lattices for different values of the condensate norm N = 1 (a) and N = 10 (b). The real and imaginary parts of ${ \mathcal P }{ \mathcal T }$ symmetric optical lattices are V0 = 0.3 and W0 = 0.05, respectively. The other parameters are set as g = 1.
