Spectral singularity and reflectionlessness in non-Hermitian (complex) Ginocchio potential
Spectral singularity and reflectionlessness in non-Hermitian (complex) Ginocchio potential
Recently, interest in scattering from complex non-Hermitian potentials has been renewed both theoretically and experimentally. When a potential becomes complex, several new features arise which may not be predicted. In this regard, we study the non-Hermitian version of the exactly solvable, versatile Ginocchio potential. We find that when it is …
