Eigenvalues from power--series expansions: an alternative approach

P. Amore, F. M. Fernandez

An appropriate rational approximation to the eigenfunction of the Schrödinger equation for anharmonic oscillators enables one to obtain the eigenvalue accurately as the limit of a…

Born-Oppenheimer approximation for a harmonic molecule

Francisco M. Fernández

We apply the Born--Oppenheimer approximation to a harmonic diatomic molecule with one electron. We compare the exact and approximate results not only for the internal degrees of fr…

On nonadiabatic calculation of dipole moments

Francisco M. Fernandez

We show that a recent non Born--Oppenheimer calculation of dipole moments exhibits obscure points and is not consistent with the well known Hellmann--Feynman theorem.

Rayleigh-Ritz variation method and connected-moments polynomial approach

Francisco M. Fernandez

We show that the connected-moments polynomial approach proposed recently is equivalent to the well known Rayleigh-Ritz variation method in the Krylov space. We compare the latter w…

Accurate eigenvalues of bounded oscillators

Francisco M. Fernandez

We calculate accurate eigenvalues of a bounded oscillator by means of the Riccati--Padé method that is based on a rational approximation to a regularized logarithmic derivative of…
