Interface free energy or surface tension: definition and basic properties
C. -E. Pfister
Interface free energy is the contribution to the free energy of a system due to the presence of an interface separating two coexisting phases at equilibrium. It is also called surf…
Non-Analyticity and the van der Waals Limit
S. Friedli, C. -E. Pfister
We study the analyticity properties of the free energy $f_\ga(m)$ of the Kac model at points of first order phase transition, in the van der Waals limit $\ga\searrow 0$. We show th…
Random-Cluster Representation of the Ashkin-Teller Model
C. -E. Pfister, Y. Velenik
We show that a class of spin models, containing the Ashkin-Teller model, admits a generalized random-cluster (GRC) representation. Moreover we show that basic properties of the usu…
Mathematical Theory of the Wetting Phenomenon in the 2D Ising Model
C. E. Pfister, Y. Velenik
We give a mathematical theory of the wetting phenomenon in the 2D Ising model using the formalism of Gibbs states. We treat the grand canonical and canonical ensembles.
