Thalmann, F and Dasgupta, C and Feinberg, D (2000) Phase diagram of a classical ﬂuid in a quenched random potential. In: Europhysics Letters, 50 (1). pp. 54-60.
We consider the phase diagram of a classical ﬂuid in the presence of a random pinning potential of arbitrary strength. Introducing replicas for averaging over the quenched disorder, we use the hypernetted chain approximation to calculate the correlations in the replicated liquid. The freezing transition of the liquid into a nearly crystalline state is studied using a density functional approach, and the liquid-to-glass transition is studied using a phenomenological replica symmetry breaking approach introduced by Mezard and Parisi. The first-order liquid-to-crystal transition is found to change to a continuous liquid-to-glass transition as the strength of the disorder is increased above a threshold value.
