Abstract:
Hydrodynamic limit for the Ginzburg-Landau $\nablaφ$ interface model was established in [5] under the periodic boundary conditions. This paper extends their results to the modified dynamics which preserve the total volume of each microscopic phase. Nonlinear partial differential equation of fourth order % \[\frac{\partial h}{\partial t} =-Δ\left[\dive\left\{(\nablaσ)(\nabla h(t,θ))\right\}\right], θ\in{\mathbb T}^d\equiv[0,1)^d,\,t>0\] % is derived as the macroscopic equation, where $σ=σ(u)$ is the surface tension of the surface with tilt $u\in\real^d$. The main tool is $H^{-2}$-method, which is a modification of $H^{-1}$-method used in [5]. The Gibbs measures associated with the dynamics are characterized.
