CP methods for the Schrödinger equation
This paper focuses on a class of piecewise perturbation methods for approximating the potential energy function when solving the one dimensional Schrödinger equation. These methods, known as constant perturbation (CP) methods, approximate the potential energy function by piecewise constants on a set of subintervals and then perform polynomial-type perturbation corrections. An error analysis is given and a simple numerical illustration.
