The one-dimensional hydrogen atom revisited

Abstract: The one dimensional Schrödinger hydrogen atom is an interesting mathematical and physical problem to study bound states, eigenfunctions and quantum degeneracy issues. This 1D physical system gave rise to some intriguing controversy over more than four decades. Presently, still no definite consensus seems to have been reached. We reanalyzed this apparently controversial problem, approaching it from a Fourier transform representation method combined with some fundamental (basic) ideas found in self-adjoint exten… Show more

“…Since the beginning of an element can lie near an extremum, in which case h i can be too large, we will enforce a similar requirement for the change in first derivative as well. Following a similar procedure, we get yet another step size from a quadratic equation with coefficients [F (4) …”

“…An alternative option for this method is to combine the above two requirements into a single fourth-order approximation and get h i by selecting the minimum in magnitude of the roots from the resulting cubic equation with coefficients [F (4) …”
