An ubiquitous three-term recurrence relation
Paolo Amore, Francisco M. Fernández
We solve an eigenvalue equation that appears in several papers about a wide range of physical problems. The Frobenius method leads to a three-term recurrence relation for the coeff…
A most misunderstood conditionally-solvable quantum-mechanical model
Francisco M. Fernández
In this paper we show that several authors have derived wrong physical conclusions from a gross misunderstanding of the exact eigenvalues and eigenfunctions of a conditionally-solv…
On a class of non-Hermitian Hamiltonians with tridiagonal matrix representation
Francisco M. Fernández
We show that some non-Hermitian Hamiltonian operators with tridiagonal matrix representation may be quasi Hermitian or similar to Hermitian operators. In the class of Hamiltonian o…
Comment on: "Bound states and the potential parameter spectrum". J. Math. Phys. \textbf{67}, 062103 (2020)
Francisco M. Fernández
We analyze the application of the "tridiagonal representation approach" (TRA) to the Schrödinger equation for some simple, exactly-solvable, quantum-mechanical models. In the case…
Comment on: "Aharonov-Bohm effect for bound states from the interaction of the magnetic quadrupole moment of a neutral particle with axial fields". Phys. Rev. A 101, 032102 (2020)
Francisco M. Fernández
We analyze recently published results about the Aharonov-Bohm effect for bound states from the interaction of the magnetic quadrupole moment of a neutral particle with axial fields…
