Position dependent mass Schrodinger equation and isospectral potentials: Intertwining operator approach

Bikashkali Midya, B. Roy, and R. Roychoudhury<br/> Here, we have studied first- and second-order intertwining approaches to generate isospectral partner potentials of position dependent (effective) mass Schrodinger equation. The second-order intertwiner is constructed directly by taking it as second-order linear differential operator with position d … [J. Math. Phys. 51, 022109 (2010)] published Tue Feb 9, 2010.
