Nonlinear pseudobosons versus hidden Hermiticity: II. The case of unbounded operators
Abstract
A close parallelism between the notions of nonlinear pseudobosons and those of an apparent nonHermiticity of observables as shown in part I (2011 J. Phys. A: Math. Theor. 44 415305) is demonstrated to survive the transition to the quantum models using an unbounded metric in the socalled standard Hilbert space of states.
