Conceptual Aspects of PT-Symmetry and Pseudo-Hermiticity: A status report

摘要: We survey some of the main conceptual developments in study PT-symmetric and pseudo-Hermitian Hamiltonian operators that have taken place during past ten years or so. offer a precise mathematical description quantum system its representations allows us to describe idea unitarization by modifying inner product Hilbert space. discuss role importance quantum-to-classical correspondence principle provides physical interpretation observables mechanics. Finally, we address problem constructing an underlying classical for unitary defined priori non-Hermitian Hamiltonian.
