Symmetric eighth algebraic order methods with minimal phase-lag for the numerical solution of the Schrödinger equation
Some new eight algebraic order symmetric eight-step methods are introduced. A direct formula for computation of the phase-lag is given for these methods. The stability properties are discussed. Numerical illustrations on the radial Schrödinger equation indicate that the new methods are more efficient than older ones.
