An alternative construction of the positive inner product for pseudo-Hermitian Hamiltonians: Examples
Ashok Das, L. Greenwood
This paper builds on our earlier proposal for construction of a positive inner product for pseudo-Hermitian Hamiltonians and we give several examples to clarify our method. We show…

An alternative construction of the positive inner product in non-Hermitian quantum mechanics
Ashok Das, L. Greenwood
Within the context of non-Hermitian quantum mechanics, we use the generators of eigenvectors of the Hamiltonian to construct a unitary inner product space. Such models have been of…
