Abstract So far, attractive , trapless Bose–Einstein condensate (BEC) has been stabilized by considering the temporal modulation of the scattering length. However, there is no scope to stabilize the repulsive , trapless BEC even in the presence of the temporal modulation of the two-body interaction. However, in the present study, we stabilize the repulsive , trapless BEC by incorporating higher-order interaction. We also discuss the possibilities of the stabilization of repulsive, trapless BEC in the presence of time-varying higher-order interaction. Additionally, we verify our analytical findings by direct numerical simulation using the split-step Crank-Nicholson method.
