Exponentially-fitted Runge-Kutta third algebraic order methods for the numerical solution of the Schrodinger equation and related problems
Exponentially and trigonometrically fitted third algebraic order Runge-Kutta methods for the numerical integration of the Schrodinger equation are developed in this paper. Numerical results obtained for several well known problems show the efficiency of the new methods.
