Sine-Gordon kink-antikink generation on spatially periodic potentials.
TL;DR: A spatially periodic perturbation can lead to a breakup of large-amplitude sine-Gordon breathers into kink and antikink solutions, each oscillating around a minimum of the perturbing potential.
Sine-Gordon breathers on spatially periodic potentials.
TL;DR: An extensive simulation program is carried out to study the behavior of sine-Gordon breathers initially at rest in the presence of perturbations that are periodic in space and constant in time and proposes some qualitative explanations valid for certain regimes.
Growth and forms of Laplacian aggregates.
TL;DR: In this paper, Niemeyer et al. investigated the shape and general morphological properties of aggregates grown following the [eta] rule and found that the fractal dimension decreases monotonically from its diffusion-limited aggregation value ([eta]=1) to a number indistinguishable from 1 at [eta][approx gt]4 while the multifractal properties become independent of [eta.
Interference effects in soliton scattering by impurities
TL;DR: In this paper, the effects of inhomogeneities on nonlinear excitation dynamics in different one-dimensional soliton-bearing systems were investigated, and the authors theoretically analyzed soliton scattering by one and two point-like impurities in the framework of perturbed sine-Gordon, nonlinear Schrodinger and Korteweg-de Vries equations.
Length scale competition in the damped sine-Gordon chain with spatiotemporal periodic driving
TL;DR: A linear stability analysis reveals that, in addition to two competing length-scales, namely, the width of the breathers and the spatial period of the driving, there is one more length-scale which plays an important role in controlling the dynamics of the system at small driving.
