Rational extension and Jacobi-type {\boldmath{}} solutions of a quantum nonlinear oscillator
arXiv:1311.5333 · doi:10.1063/1.4835575
Abstract
We construct a rational extension of a recently studied nonlinear quantum oscillator model. Our extended model is shown to retain exact solvability, admitting a discrete spectrum and corresponding closed-form solutions that are expressed through Jacobi-type exceptional orthogonal polynomials.
