Particle correlation from uncorrelated non Born-Oppenheimer SCF wavefunctions
Paolo Amore, Francisco M. Fernández
We analyse a nonadiabatic self-consistent field method by means of an exactly-solvable model. The method is based on nuclear and electronic orbitals that are functions of the carte…
Prony's method and the connected-moments expansion
Francisco M. Fernández
We show that Prony's method provides the full solution to the nonlinear equations of the connected--moments expansion (CMX). Knowledge of all the parameters in the CMX ansatz is us…
Wronskian method and the Schrödinger eigenvalue march
Francisco M. Fernández
We compare the Wronskian method (WM) and the Schrödinger eigenvalue march or canonical function method (SEM--CFM) for the calculation of the energies and eigenfunctions of the Schr…
Solution to the Equations of the Moment Expansions
Paolo Amore, Francisco M. Fernández
We develop a formula for matching a Taylor series about the origin and an asymptotic exponential expansion for large values of the coordinate. We test it on the expansion of the ge…
Resonances for symmetric two-barrier potentials
Francisco M. Fernández
We describe a method for the accurate calculation of bound-state and resonance energies for one-dimensional potentials. We calculate the shape resonances for symmetric two-barrier…
Comment on: "Non-relativistic treatment of diatomic molecules interacting with generalized Kratzer potential in hyperspherical coordinates"
Francisco M. Fernández
We argue that the textbook method for solving eigenvalue equations is simpler, more elegant and efficient than the Asymptotic Iteration Method (AIM) applied in J. Phys. A {\bf 44}…
Wronskian method for bound states
Francisco M. Fernández
We propose a simple and straightforward method based on Wronskians for the calculation of bound--state energies and wavefunctions of one--dimensional quantum--mechanical problems.…
