We consider the case of a deformable material interface between two immiscible moving media, both of them being magnetizable, stressing the time dependence of the metric at the interface. This introduces a nonlinear term, proportional to the mean curvature, in the surface dynamical equations of...

A theoretical model is presented for the study of the scattering of phonons at an extended inhomogeneous boundary separating thin solid monatomic films. The model system consists of two solid films with otherwise stress-free surfaces on either side of an atomic well boundary. The coherent...

We study the steady-state structure and dynamics of a 2-d Ising interface placed in an inhomogeneous external field with a sigmoidal profile which moves with velocity ve. In the strong coupling limit, the problem maps onto an asymmetric exclusion process involving motion of particles in 1-d with...

The peculiar phase-ordering properties of a lattice of coupled chaotic maps studied recently (Lemaı̂tre, Chaté, Phys. Rev. Lett. 82 (1999) 1140) are revisited with the help of detailed investigations of interface motion. It is shown that “normal”, curvature-driven-like domain growth is...

We present a study of dynamical scaling and domain growth in a nonpotential system that models Rayleigh–Bénard convection in a rotating cell. In d=1, dynamical scaling holds, but the nonpotential terms modify the characteristic growth law with a crossover from logarithmic to linear in time....
