Jacobi exceptional orthogonal polynomials for extended Scarf I potentials with position-dependent mass

Christiane Quesne

We show that the Scarf I potential problem in a position-dependent mass background of the type $m (I^\pm; x) = (1 + I^\pm sin x)^{- 2}$ , $0 < I^\pm < 1$ , can be solved by using a point canonical t…

Rationally-extended radial harmonic oscillator in a position-dependent mass background

Christiane Quesne

We show that the radial harmonic oscillator problem in the position-dependent mass background of the type $m (I^\pm; r) = (1 + I^\pm r^{2})^{- 2}$ , $I^\pm > 0$ , can be solved by using a point canonic…
