PT-symmetric square well and the associated SUSY hierarchies
B. Bagchi, S. Mallik, C. Quesne
The PT-symmetric square well problem is considered in a SUSY framework. When the coupling strength lies below the critical value where PT symmetry becomes sp…

Pseudo-Hermiticity, weak pseudo-Hermiticity and eta-orthogonality condition
B. Bagchi, C. Quesne
We discuss certain features of pseudo-Hermiticity and weak pseudo-Hermiticity conditions and point out that, contrary to a recent claim, there is no inconsistency if the correct or…

PT-symmetric non-polynomial oscillators and hyperbolic potential with two known real eigenvalues in a SUSY framework
B. Bagchi, C. Quesne
Extending the supersymmetric method proposed by Tkachuk to the complex domain, we obtain general expressions for superpotentials allowing generation of quasi-exactly solvable PT-sy…
