G. Avdelas et Te. Simos, On variable-step methods for the numerical solution of Schrodinger equation and related problems, COMPUT CHEM, 25(1), 2001, pp. 3-13
In this paper we present a review for the construction of variable-step met
hods for the numerical integration of the Schrodinger equation. Phase-lag a
nd stability are investigated. The methods are variable-step because of a s
imple natural error control mechanism. Numerical results obtained for coupl
ed differential equations arising from the Schrodinger equation and for the
wave equation show the validity of the approach presented. (C) 2001 Elsevi
