In this paper we propose a modified Lie-type spectral splitting approximationwhere the external potential is of quadratic type. It is proved that we canapproximate the solution to a one-dimensional nonlinear Schroedinger equationby solving the linear problem and treating the nonlinear term separately, witha rigorous estimate of the remainder term. Furthermore, we show by means ofnumerical experiments that such a modified approximation is more efficient thanthe standard one.
