On the application of statistical mechanics to diatomic molecules
Francisco M. Fernández
We argue that the results proposed recently for the electronic state of do not exhibit any physical utility because the canonical vibrational…
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…
Highly accurate potential energy curves for the hydrogen molecule ion
Francisco Marcelo Fernández, Javier Garcia
Potential energy surfaces of the hydrogen molecular ion H in the Born-Oppenheimer approximation are computed by means of the Riccati-Padé method (RPM). The convergence proper…
