Breathing dynamics in heteropolymer DNA
(CELL PRESS, 2007-04)
While the statistical mechanical description of DNA has a long tradition, renewed interest in DNA melting from a physics perspective is nourished by measurements of the fluctuation dynamics of local denaturation bubbles ...
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 ...
Nanostructure and velocity of field-driven solid-on-solid interfaces moving under a phonon-assisted dynamic
(American Physical Society, 2007-07)
The nanoscopic structure and the stationary propagation velocity of (1+1)-dimensional solid-on-solid interfaces in an Ising lattice-gas model, which are driven far from equilibrium by an applied force, such as a magnetic ...
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 ...
Local aging phenomena close to magnetic surfaces
(American Physical Society, 2007-09)
Surface aging phenomena are discussed for semi-infinite systems prepared in a fully disordered initial state and then quenched to or below the critical point. In addition to solving exactly the semi-infinite Ising model ...
