Abnormal Rolls and Regular Arrays of Disclinations in Homeotropic Electroconvection
Axel G. Rossberg, Nandor Eber, Agnes Buka +1
We present the first quantitative verification of an amplitude description for systems with (nearly) spontaneously broken isotropy, in particular for the recently discovered abnorm…
Optical characterization of chevron texture formation in nematic electroconvection
H. Amm, R. Stannarius, A. G. Rossberg
We characterize the director structures in electroconvection patterns of nematic liquid crystals by means of polarising microscopy. This study was stimulated by a theory put forwar…
Pattern Formation from Defect Chaos --- A Theory of Chevrons
A. G. Rossberg, L. Kramer
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 defe…
Weakly Nonlinear Theory of Pattern-Forming Systems with Spontaneously Broken Isotropy
A. G. Rossberg, A. Hertrich, L. Kramer +1
Quasi two-dimensional pattern forming systems with spontaneously broken isotropy represent a novel symmetry class, that is experimentally accessible in electroconvection of homeotr…
