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

Abstract

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 $H_{\beta }=[p+\mathrm{i}\beta \nu (x){]}^2/2m+V(x)$.
