Optimizing a Hybrid Two-Step Method for the Numerical Solution of the Schrödinger Equation and Related Problems with Respect to Phase-Lag

[摘要] We use a methodology of optimization of the efficiency of a hybrid two-stepmethod for the numerical solution of the radial Schrödinger equation and related problems withperiodic or oscillating solutions. More specifically, we study how the vanishing of the phase-lagand its derivatives optimizes the efficiency of the hybrid two-step method.
