The consistency in these results became an important justification and motivated a very strong growth in theoretical physics in the late 50's and 60's.
 
==Application: RPA Ground State of an interacting bosonic system ==
 
The RPA vacuum <math>\left|\mathbf{RPA}\right\rangle</math> for a bosonic system can be expressed in terms of non-correlated bosonic vacuum <math>\left|\mathbf{MFT}\right\rangle</math> and original boson excitations <math>\mathbf{a}_{i}^{\dagger}</math>
