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 ...
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 ...
Current distribution in systems with anomalous diffusion: renormalization group approach

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 ...
Influence of local carrying capacity restrictions on stochastic predator-prey models

Relaxation of photoinduced spins and carriers in ferromagnetic InMnSb films
(AIP Publishing, 2007-04)
The authors report time resolved measurements and control of photoinduced spin and carrier relaxations in InMnSb ferromagnetic films with 2% Mn content (grown by low-temperature molecular beam epitaxy) using femtosecond ...
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 ...
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 ...
