摘要：
In this paper, we study the localized nonlinear matter waves in one-dimensional Bose-Einstein condensates with spatiotemporally modulated two- and three-body interactions and time-dependent external potentials. By means of similarity transformation, two exact solutions of the one-dimensional cubic-quintic Gross-Pitaevskii equation are obtained explicitly. It is demonstrated that both attractive two- and three-body interactions and attractive two-body plus repulsive three-body interactions support localized nonlinear matter waves in Bose-Einstein condensates trapped in time-dependent external potentials. The dynamics of the localized nonlinear matter wave is analyzed and some breathing and quasi-breathing solutions are found.
