Scattering theory with localized non-Hermiticities

Original language description

In the context of the recent interest in solvable models of scattering mediated by non-Hermitian Hamiltonians (cf. H. F. Jones, Phys. Rev. D 76, 125003 (2007)) we show that the well-known variability of the ad hoc choice of the metric Theta which definesthe physical Hilbert space of states can help us to clarify several apparent paradoxes. We argue that with a suitable Theta, a fully plausible physical picture of the scattering can be recovered. Quantitatively, our new recipe is illustrated on an exactly solvable toy model.
