摘要：

The PT-symmetric square well problem is considered in a SUSY framework. When the coupling strength Z lies below the critical value Z(O)((C)) where PT symmetry becomes spontaneously broken, we find a hierarchy of SUSY partner potentials, depicting an unbroken SUSY situation and reducing to the family of sect-like potentials in the Z --> O limit. For Z above Z(O)((c)), there is a rich diversity of SUSY hierarchies, including some with PT-symmetry breaking and some with partial PT-symmetry restoration.
