Classes of Balanced Gain-and-Loss Waveguides as Non-Hermtian Potential Hierarchies
In this work, we report the construction of different classes of complex-valued refractive index landscapes, with real spectra, in the framework of the factorization method. The particular case of guiding hyperbolic-type profiles is considered in the <inline-formula><math xmlns="http:/...
