Abnormal Rolls and Regular Arrays of Disclinations in Homeotropic Electroconvection

patt-sol 2009-10-31 v1 Pattern Formation and Solitons

Abstract

We present the first quantitative verification of an amplitude description for systems with (nearly) spontaneously broken isotropy, in particular for the recently discovered abnormal-roll states. We also obtain a conclusive picture of the 3d director configuration in a spatial period doubling phenomenon involving disclination loops (CRAZY rolls). The first observation of two Lifshitz frequencies in electroconvection is reported.
