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 ...
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 ...
Transverse beam spin asymmetries in forward-angle elastic electron-proton scattering
(American Physical Society, 2007-08-31)
We have measured the beam-normal single-spin asymmetry in elastic scattering of transversely polarized 3 GeV electrons from unpolarized protons at Q(2)=0.15, 0.25 (GeV/c)(2). The results are inconsistent with calculations ...
Glueball spectrum of pure Yang-Mills theory in 2+1 dimensions
(American Physical Society, 2007-09)
We present details of the analytic computation of the spectrum of lowest spin glueballs in pure Yang-Mills theory in 2+1 dimensions. The new ingredient is provided by the conjectured new nontrivial expression for the ...
Coarsening of "clouds" and dynamic scaling in a far-from-equilibrium model system
(American Physical Society, 2007-04)
A two-dimensional lattice gas of two species, driven in opposite directions by an external force, undergoes a jamming transition if the filling fraction is sufficiently high. Using Monte Carlo simulations, we investigate ...
Field-theory approaches to nonequilibrium dynamics
