Abstract

In this paper we study the quantization of the nonlinear oscillator introduced by Mathews and Lakshmanan. This system with position-dependent mass allows a natural quantization procedure and is shown to display shape invariance. Its energy spectrum is found by factorization. The linear harmonic oscillator appears as the λ 0 limit of this nonlinear oscillator, whose energy spectrum and eigenfunctions are compared to the linear ones.
