摘要：

A non-Hermitian generalisation of the Marsden-Weinstein reduction method is introduced to construct families of quantum PT-symmetric superintegrable models over an n-dimensional sphere S-n. The mechanism is illustrated with one-and two-dimensional examples, related to u(2) and u(3) Lie algebras respectively, providing new quantum models with real spectra and spontaneous PT-symmetric breaking. In certain limits, the models reduce to known non-Hermitian systems and complex extensions of previously studied real superintegrable systems.
