Pseudo-Hermiticity, weak pseudo-Hermiticity and eta-orthogonality condition

摘要

We discuss certain features of pseudo-Hermiticity and weak pseudo-Hermiticity conditions and point out that, contrary to a recent claim, there is no inconsistency if the correct orthogonality condition is used for the class of pseudo-Hermitian, PT-symmetric Hamiltonians of the type H-beta = [p + ibetav (x)](2)/2m + V (x).
