L. Leuzzi
  Spin model for inverse freezing in amorphous materials
    We analyze the Blume-Emery-Griffiths model with disordered
    magnetic interaction that displays the inverse freezing
    phenomenon. The behavior of this spin-1 model in crystal field is
    studied throughout the phase diagram and the transition and
    spinodal lines for the model are computed using the Full Replica
    Symmetry Breaking Ansatz that always yields a thermodynamically
    stable phase.  We compare the results both with the formulation of
    the same model in terms of Ising spins on lattice gas, where no
    reentrance takes place, and with the model with generalized spin
    variables recently introduced by Schupper and Shnerb
    [Phys. Rev. Lett. {\bf 93} 037202 (2004)], for which the
    reentrance is enhanced as the ratio between the degeneracy of full
    to empty sites increases. The simplest version of all these
    models, known as the Ghatak-Sherrington model, turns out to hold
    all the general features characterizing an inverse transition to
    an amorphous phase, including the right thermodynamic behavior.
