Line 13: === Ground state of an interacting bosonic system=== The RPA vacuum <math>\left\|\~~mathbf~~mathrm{RPA}\right\rangle</math> for a bosonic system can be expressed in terms of non-correlated bosonic vacuum <math>\left\|\~~mathbf~~mathrm{MFT}\right\rangle</math> and original boson excitations <math>\mathbf{a}_{i}^{\dagger}</math> :<math>\left\|\mathrm{RPA}\right\rangle=\mathcal{N}\mathbf{e}^{Z_{ij}\mathbf{a}_{i}^{\dagger}\mathbf{a}_{j}^{\dagger}/2}\left\|\mathrm{MFT}\right\rangle</math>
