Limit distributions and scaling functions
We discuss the asymptotic behaviour of models of lattice polygons, mainly on the square lattice. In particular, we focus on limiting area laws in the uniform perimeter ensemble where, for fixed perimeter, each polygon of a given area occurs with the same probability. We relate limit distributions to the scaling behaviour of the associated perimeter and area generating functions, thereby providi...
متن کاملHydrodynamic Scaling Limit of Continuum Solid-on-solid Model
A fourth-order nonlinear evolution equation is derived from a microscopic model for surface diffusion, namely, the continuum solid-on-solid model. We use the method developed by Varadhan for the computation of the hydrodynamic scaling limit of nongradient models. What distinguishes our model from other models discussed so far is the presence of two conservation laws for the dynamics in a nonper...
متن کاملContinuum extrapolation of BK with staggered fermions
We report on recent progress in the calculation of BK using HYP-smeared staggered fermions on the MILC asqtad lattices. Our main focus is on the continuum extrapolation, which is done using (up to) four different lattice spacings—a ≈ 0.12, 0.09, 0.06 and 0.045 fm. Since Lattice 2010, we have reduced the statistical errors on the a ≈ 0.09 fm lattices by a factor of ∼ 3, and roughly doubled the s...
متن کاملThe Quenched Continuum Limit
Our increasing ability to carry out unquenched simulations means that the quenched approximation is no longer required. There is an outstanding issue associated with the quenched continuum limit, however, which we address here. At the same time we point out the ingredients that are necessary to obtain an accurate result in the continuum limit, since these ingredients will also be important for ...
متن کاملOn Homogenization and Continuum Scaling Limit of Some Gradient Perturbations of a Massless Free Field
We study the continuum scaling limit of some statistical mechanical models de ned by convex Hamiltonians which are gradient perturbations of a massless free eld. By proving a central limit theorem for these models, we will show that their long distance behavior is identical to a new (homogenized) continuum massless free eld. We shall also obtain some new bounds on the two point functions of the...
