    "abstract": "We introduce a novel semiclassical approach to the Lipkin model. In this way\nthe well-known phase transition arising at the critical value of the coupling\nis intuitively understood. New results -- showing for strong couplings the\nexistence of a threshold energy which separates deformed from undeformed states\nas well as the divergence of the density of states at the threshold energy --\nare explained straightforwardly and in quantitative terms by the appearance of\na double well structure in a classical system corresponding to the Lipkin\nmodel. Previously unnoticed features of the eigenstates near the threshold\nenergy are also predicted and found to hold.",
