Abstract
The effects of lattice anisotropy on the dynamics of an interface between coexisting phases is studied using a Ginzburg-Landau model in two dimensions that incorporates an anisotropic surface tension. It is shown that the anisotropy does not change growth exponents, but the kinetic coefficient in the Langevin equation, which describes the dynamics of the interface, turns out to be anisotropic. Thus the shapes of growing domains are different from the equilibrium crystal shape.Keywords
