Higher order cor-rections to the EGPE have also been developed [30–32]. In particular, we systematically studied the self-bound droplets of dipolar and binary condensates [33,34] using Webq in the hermitian form. The q-Fock space Fq(H) is the completion of this pre-Hilbert space. If q = 1 or q = −1, one must ﬁrst divide out by a null space, and one obtains the usual symmetric and antisymmetric Fock spaces. If q = 0 one obtains the usual full Fock space. We restrict our attention to the case −1 < q < 1. We let H[0] = CI and helena tillmann
