Solvable rational extensions of the Morse and Kepler-Coulomb potentials (1103.5023v1)
Published 25 Mar 2011 in math-ph, math.MP, and quant-ph
Abstract: We show that it is possible to generate an infinite set of solvable rational extensions from every exceptional first category translationally shape invariant potential. This is made by using Darboux-B\"acklund transformations based on unphysical regular Riccati-Schr\"odinger functions which are obtained from specific symmetries associated to the considered family of potentials.
