Abstract
We construct a variational wave function for inhomogeneous weakly interacting Bose--Einstein condensates beyond the mean-field approximation by incorporating -body correlations. From our numerical results calculated for a system trapped by a one-dimensional harmonic oscillator, the -body correlations give a contribution comparable to the mean- field energy toward lowering the ground-state energy.
