Pseudo-hermiticity versus PT symmetry: spectral breakdown in nearly degenerate quantum energy eigenvalues

Published Jan 14, 2019• 0 citations

Abstract

It is interesting to note that pseudo-hermiticity condition fails to preserve spectral invariant nature in nearly degenerate quantum states of single and double well operators.In other words no spectral similarity exists between nearly degenerate energy eigenvalues of Hermitian operator and corresponding PT-symmetry operator

Pseudo-Hermiticity versus PT symmetry: The necessary condition for the reality of the spectrum of a non-Hermitian Hamiltonian

Ali Mostafazadeh

We introduce the notion of pseudo-Hermiticity and show that every Hamiltonian with a real spectrum is pseudo-Hermitian. We point out that all the PT-symmetric non-Hermitian Hamiltonians studied in the literature belong to the class of pseudo-Hermitian Hamiltonians, and argue that the basic structure responsible for the particular spectral properties of these Hamiltonians is their pseudo-Hermiticity. We explore the basic properties of general pseudo-Hermitian Hamiltonians, develop pseudosupersymmetric quantum mechanics, and study some concrete examples, namely the Hamiltonian of the two-component Wheeler–DeWitt equation for the FRW-models coupled to a real massive scalar field and a class of pseudo-Hermitian Hamiltonians with a real spectrum.

Pseudo-Hermiticity versus PT-symmetry III: Equivalence of pseudo-Hermiticity and the presence of antilinear symmetries

Ali Mostafazadeh

We show that a diagonalizable (non-Hermitian) Hamiltonian H is pseudo-Hermitian if and only if it has an antilinear symmetry, i.e., a symmetry generated by an invertible antilinear operator. This implies that the eigenvalues of H are real or come in complex conjugate pairs if and only if H possesses such a symmetry. In particular, the reality of the spectrum of H implies the presence of an antilinear symmetry. We further show that the spectrum of H is real if and only if there is a positive-definite inner-product on the Hilbert space with respect to which H is Hermitian or alternatively there is a pseudo-canonical transformation of the Hilbert space that maps H into a Hermitian operator.

Asymmetry nature in symmetry breakdown: Anti-PT-symmetry

Biswanath Rath

We discover present anti-PT-symmetry operator is a problematic non-hermit operator. However the the usage of similarity transformation we seriously change to a new non-hermit operator underneath the identical commutating operator. Interestingly the use of new shape of PT-symmetry we reproduce preceding experimental outcomes and propose new nature of asymmetry in symmetry breakdown.
