Controlling surface morphologies by time-delayed feedback
(American Physical Society, 2007-06-25)
We propose a method to control the roughness of a growing surface via a time-delayed feedback scheme. The method is very general and can be applied to a wide range of nonequilibrium growth phenomena, from solid-state epitaxy ...
Inhomogeneous exclusion processes with extended objects: The effect of defect locations
(American Physical Society, 2007-11)
We study the effects of local inhomogeneities, i.e., slow sites of hopping rate q < 1, in a totally asymmetric simple exclusion process for particles of size l >= 1 (in units of the lattice spacing). We compare the simulation ...
Power spectra of the total occupancy in the totally asymmetric simple exclusion process
(American Physical Society, 2007-07-13)
As a solvable and broadly applicable model system, the totally asymmetric exclusion process enjoys iconic status in the theory of nonequilibrium phase transitions. Here, we focus on the time dependence of the total number ...
