Title: Lattice gas analogue of the Sherrington-Kirkpatrick model: a paradigm for the glass transition
Abstract: We investigate the connection between the well known Sherrington-Kirkpatrick Ising spin glass and the corresponding lattice gas model by analysing the relation between their thermodynamical functions. We present results of replica approach in the replica-symmetric approximation and discuss its stability as a function of temperature and external source. Then we examine the effects of first-order replica symmetry breaking at zero temperature. Finally, we compare Sherrington-Kirkpatrick results with ours and suggest in which sense the latter could be relevant to a description of the structural glass transition.
