Two-dimensional particle motion in a random potential under ac bias
Maxim A. Makeev, Imre Derényi, Albert-László Barabási
We study the Brownian motion of a single particle coupled to an external ac field in a two-dimensional random potential. We find that for small fields a large-scale vorticity patte…

Morphology of Ion-Sputtered Surfaces
Maxim Makeev, Rodolfo Cuerno, Albert-László Barabási
We derive a stochastic nonlinear continuum theory to describe the morphological evolution of amorphous surfaces eroded by ion bombardment. Starting from Sigmund's theory of sputter…
