Tight-binding reproduces spatial intensity distributions but fails to capture complex oscillatory phase dynamics when benchmarked against exact z-dependent SUSY solutions in longitudinally modulated PT-symmetric waveguides.
The ground state ψg is symmetric ( Pψ g(x) = ψg(x)), while the excited state ψe is antisymmetric (Pψ e(x) = −ψe(x)), where the parity operator is defined as Pf (x) ≡f (−x)
