Abstract
The ground-state energy of the Lipkin-Meshkov-Glick hamiltonian was estimated by the Bogoliubov-Lieb inequalities which involve the atomic coherent states. It was found that the so-called Q-representation of the pseudospin hamiltonian provides a good estimation of the ground-state energy. Furthermore, nuclear phase transitions can be vividly described by the deviations of the pseudospin from the southpole of the so-called Bloch sphere.
