On the Role of the Normalization Factors $kappa_n$ and of the Pseudo-Metric ${cal P} neq {cal P}^dag$ in Crypto-Hermitian Quantum Models
Among ${cal P}$-pseudo-Hermitian Hamiltonians $H ={cal P}^{-1} H^dagger {cal P}$ with real spectra, the ''weaklypseudo-Hermitian" ones (i.e., those employing non-self-adjoint ${cal P} neq {cal P}^dagger$) form a remarkable subfamily. Welist some reasons why it deserves a special atte...
