Non linear pseudo-bosons versus hidden Hermiticity. II: The case of
unbounded operators

Fabio Bagarello, Miloslav Znojil
Parallels between the notions of nonlinear pseudobosons and of an apparent
non-Hermiticity of observables as shown in paper I (arXiv: 1109.0605) are
demonstrated to survive the transition to the quantum models based on the use
of unbounded metric in the Hilbert space of states.
