Pattern Formation from Defect Chaos --- A Theory of Chevrons

, 1997
For over 25 years it is known that the roll structure of electroconvection (EC) in the dielectric regime in planarly aligned nematic liquid crystals has, after a transition to defect chaos, the tendency to form chevron structures.

Numerical study of domain coarsening in anisotropic stripe patterns

, 2004
We study the coarsening of two-dimensional smectic polycrystals characterized by grains of oblique stripes with only two possible orientations. For this purpose, an anisotropic Swift-Hohenberg equation is solved. For quenches close enough to the onset of

Coexistence of stable branched patterns in anisotropic inhomogeneous systems

New Journal of Physics, 2015
A new class of pattern forming systems is identified and investigated: anisotropic systems that are spatially inhomogeneous along the direction perpendicular to the preferred one.

Fundamental scaling laws of on-off intermittency in a stochastically driven dissipative pattern forming system

, 2001
Noise driven electroconvection in sandwich cells of nematic liquid crystals exhibits on-off intermittent behaviour at the onset of the instability. We study laser scattering of convection rolls to characterize the wavelengths and the trajectories of the ...

Flexoelectricity and pattern formation in nematic liquid crystals

, 2011
We present in this paper a detailed analysis of the flexoelectric instability of a planar nematic layer in the presence of an alternating electric field (frequency $\omega$), which leads to stripe patterns (flexodomains) in the plane of the layer.

On two-dimensional finite amplitude electro-convection in a dielectric liquid induced by a strong unipolar injection [PDF]

, 2015
The hydrodynamic stability of a dielectric liquid subjected to strong unipolar injection is numerically investigated. We determined the linear criterion Tc (T being the electric Rayleigh number) and finite amplitude one Tf over a wide range of the ...
