Pseudo-Hermitian approach to energy-dependent Klein-Gordon models
The relativistic Klein-Gordon system is studied as an illustration of Quantum
Mechanics using non-Hermitian operators as observables. A version of the model
is considered containing a generic coordinate- and energy-dependent
phenomenological mass-term . We show how similar systems may be
assigned a pair of the linear, energy-independent left- and right-acting
Hamiltonians with quasi-Hermiticity property and, hence, with the standard
probabilistic interpretation.Comment: 2nd Int. Workshop "Pseudo-Hermitian Hamiltonians in Quantum Physics"
