Calculation of the Hidden Symmetry Operator in PT-Symmetric Quantum Mechanics
Carl M. Bender, Peter N. Meisinger, Qinghai Wang
In a recent paper it was shown that if a Hamiltonian H has an unbroken PT symmetry, then it also possesses a hidden symmetry represented by the linear operator C. The operator C co…

All Hermitian Hamiltonians Have Parity
Carl M. Bender, Peter N. Meisinger, Qinghai Wang
It is shown that if a Hamiltonian is Hermitian, then there always exists an operator P having the following properties: (i) P is linear and Hermitian; (ii) P commutes with H; (…

Two-Point Green's Function in PT-Symmetric Theories
Carl M. Bender, Stefan Boettcher, Peter N. Meisinger +1
The Hamiltonian with is non-Hermitian, but the energy levels are real and positive as a consequence of symmetry.…
