On the use of CP methods for the numerical solution of the Schrodinger equation
Veerle Ledoux · AIP conference proceedings · 2012
One of the main scientific achievements of L. Gr. Ixaru concerns the formulation of CP methods for the numerical solution of the Schrodinger equation. The first ideas were described in the seventies but the CP methods still prove to be very efficient for not only the one-dimensional time-independent Schrodinger equation but also for Sturm-Liouville problems, coupled channel Schrodinger equations and two-dimensional Schrodinger problems. We summarize here the main ideas and discuss the use of a CP method for the single channel (one-dimensional) equation as well as for the multichannel equation.
