Spectral splitting method for nonlinear Schrödinger equations with quadratic potential

•We give an approximate solution to nonlinear Schrödinger equations.•We separately treat the linear Schrödinger equation and the nonlinear term.•We give a precise estimate of the remainder term.•We compare the modified spectral splitting approximation with the standard one. In this paper we propose...
