Abstract
In this work we investigate the differences arising in the one-body operator and the correlation parameter when the Lipkin-Meshkov-Glick model is deformed. We calculate these functions exactly and by means of the time-dependent Hartree-Fock approximation (TDHF). We observe that the exact and the TDHF results are much closer to each other in the deformed case.
