Two-dimensional particle motion in a random potential under ac bias (2004)
Makeev, Maxim A., Derényi, Imre, Barabási, Albert-László
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 pattern of the...

As extensive experimental studies have shown, under certain conditions, ion bombardment of solid targets induces a random (self-affine) morphology on the ion-eroded surfaces. The rough morphology...

Off-normal ion bombardment of solid targets with energetic particles often leads to development of periodically modulated structures on the surfaces of eroded materials. Ion-induced surface...
Ion-Induced Surface Diffusion in Ion Sputtering (1997)
Makeev, Maxim A., Barabasi, Albert-Laszlo
Ion bombardment is known to enhance surface diffusion and affect the surface morphology. To quantify this phenomenon we calculate the ion-induced diffusion constant and its dependence on the ion...
