Numerical Evidence that the Perturbation Expansion for a Non-Hermitian PT -Symmetric Hamiltonian is Stieltjes
Recently, several studies of non-Hermitian Hamiltonians having PT symmetry have been conducted. Most striking about these complex Hamiltonians is how closely their properties resemble those of conventional Hermitian Hamiltonians. This paper presents further evidence of the similarity of these Hamiltonians to Hermitian Hamiltonians by examining the summation of the divergent weak-coupling pertur...
متن کاملSupersymmetric Solution of PT-/Non-PT-Symmetric and Non-Hermitian Morse Potential via Hamiltonian Hierarchy Method
Supersymmetric solution of PT-/non-PT-symmetric and non-Hermitian Morse potential is studied to get real and complex-valued energy eigenvalues and corresponding wave functions. Hamiltonian Hierarchy method is used in the calculations. PACS numbers: 03.65.-w; 03.65.Ge
متن کاملA Possible Method for Non-Hermitian and Non-PT-Symmetric Hamiltonian Systems
A possible method to investigate non-Hermitian Hamiltonians is suggested through finding a Hermitian operator η+ and defining the annihilation and creation operators to be η+ -pseudo-Hermitian adjoint to each other. The operator η+ represents the η+ -pseudo-Hermiticity of Hamiltonians. As an example, a non-Hermitian and non-PT-symmetric Hamiltonian with imaginary linear coordinate and linear mo...
متن کاملMetrics and isospectral partners for the most generic cubic PT - symmetric non - Hermitian Hamiltonian Paulo
We investigate properties of the most general PT -symmetric non-Hermitian Hamiltonian of cubic order in the annihilation and creation operators as a ten parameter family. For various choices of the parameters we systematically construct an exact expression for a metric operator and an isospectral Hermitian counterpart in the same similarity class by exploiting the isomorphism between operator a...
متن کاملNon-Hermitian matrix description of the PT −symmetric anharmonic oscillators
The PT −symmetric differential Schrödinger equation Hψ = Eψ with the operator H = H(x) = p + a x + i β x + c x + i δ x ≡ H∗(−x) on L2(−∞,∞) is studied. At a > 0 it is re-arranged as a linear algebraic diagonalization. With rigorous proof, our non-variational construction of bound states offers an infinite-dimensional analogue to the recent finite-dimensional quasi-exact solution available at th...
