Wulff shapes and the critical nucleus for a triangular Ising lattice

Equilibrium Wulff shapes and interfacial energies of two-dimensional ‘‘crystals’’ on a triangular lattice are considered. Asymptotic approximations are constructed for both the shapes and energies in the limit T→0 where crystals are close to perfect hexagons, and the limit T→Tc ~critical temperature! where crystals have near-circular shapes. The intermediate temperature region is studied numeri...

The High Temperature Ising Model on the Triangular Lattice is a Critical Bernoulli Percolation Model

We define a new percolation model by generalising the FK representation of the Ising model, and show that on the triangular lattice and at high temperatures, the critical point in the new model corresponds to the Ising model. Since the new model can be viewed as Bernoulli percolation on a random graph, our result makes an explicit connection between Ising percolation and critical Bernoulli perc...

A necklace of Wulff shapes

Abstract: In a probabilistic model of a film over a disordered substrate, Monte-Carlo simulations show that the film hangs from peaks of the substrate. The film profile is well approximated by a necklace of Wulff shapes. Such a necklace can be obtained as the infimum of a collection of Wulff shapes resting on the substrate. When the random substrate is given by iid heights with exponential dist...

XXZ and Ising spins on the triangular kagome lattice

The recently fabricated two-dimensional magnetic materials Cu9X2 cpa 6 ·xH2O cpa=2-carboxypentonic acid and X=F,Cl,Br have copper sites which form a triangular kagome lattice TKL , formed by introducing small triangles “a-trimers” inside of each kagome triangle “b-trimer” . We show that in the limit where spins residing on b-trimers have Ising character, quantum fluctuations of XXZ spins residi...

Surface tension in the dilute Ising model. The Wulff construction

We study the surface tension and the phenomenon of phase coexistence for the Ising model on Z (d > 2) with ferromagnetic but random couplings. We prove the convergence in probability (with respect to random couplings) of surface tension and analyze its large deviations : upper deviations occur at volume order while lower deviations occur at surface order. We study the asymptotics of surface ten...
