Ss. Avancini et al., CORRELATIONS STUDIES IN THE Q-DEFORMED TIME-DEPENDENT HARTREE-FOCK APPROXIMATION, Journal of physics. A, mathematical and general, 28(3), 1995, pp. 701-709
In this work we investigate the differences arising in the one-body op
erator and the correlation parameter when the Lipkin-Meshkov-Glick mod
el is deformed. We calculate these functions exactly and by means of t
he time-dependent Hartree-Fock approximation (TDHF). We observe that t
he exact and the TDHF results are much closer to each other in the def
ormed case.
