On the quantum-mechanical singular harmonic oscillator
Francisco M. Fernández
We obtain the eigenvalues and eigenfunctions of the singular harmonic oscillator by means of the simple and straightforward Frobenius (power-series) method. F…

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…
