Pinning and locking of discrete waves
نویسنده
چکیده
We discuss the behavior of rotating and traveling waves { such as traveling fronts and pulses { in partial diierential equations with continuous symmetry groups under perturbations that break the continuous symmetries but preserve some discrete (lattice) symmetries. Our theory provides a rigorous and universal framework for understanding pinning, depinning and locking of discrete rotating and traveling waves.

Universality of Crystallographic Pinning
We study traveling waves for reaction diffusion equations on the spatially discrete domain Z2. The phenomenon of crystallographic pinning occurs when traveling waves become pinned in certain directions despite moving with non-zero wave speed in nearby directions. In [1] it was shown that crystallographic pinning occurs for all rational directions, so long as the nonlinearity is close to the saw...

Using numerical simulations, we observe phase locking, Arnold tongues, and Devil’s staircases for vortex lattices driven at varying angles with respect to an underlying superconducting periodic pinning array. This rich structure should be observable in transport measurements. The transverse V (I) curves have a Devil’s staircase structure, with plateaus occurring near the driving angles along sy...

متن کاملDepinning Transitions in Discrete Reaction-Diffusion Equations
We consider spatially discrete bistable reaction-diffusion equations that admit wave front solutions. Depending on the parameters involved, such wave fronts appear to be pinned or to glide at a certain speed. We study the transition of traveling waves to steady solutions near threshold and give conditions for front pinning (propagation failure). The critical parameter values are characterized a...
متن کاملObservation of vortex pinning in Bose-Einstein condensates.
We report the observation of vortex pinning in rotating gaseous Bose-Einstein condensates. Vortices are pinned to columnar pinning sites created by a corotating optical lattice superimposed on the rotating Bose-Einstein condensates. We study the effects of two types of optical lattice: triangular and square. In both geometries we see an orientation locking between the vortex and the optical lat...
