We also use these coherent states to analyse qualitatively the suppression of the second order ground-state energy phase transition of this model. © 1993.358-362engq-deformed variational study of the Lipkin-Meshkov-Glick model via coherent statesArtigo10.1016/0375-9601(93)90190-BWOS:A1993KU26700002Acesso restrito2-s2.0-0004614712
