Suppression of BEC wave packet width varying by interaction engineering. The solid line represents the FWHM of the wave packet under a timely constant attractive interaction Ng(x) = −0.3(x + 10), while the dashed line represents the FWHM of the wave packet under a timely engineered interaction. The corresponding densities are shown in Figs.
