Abstract

We investigate the response of electroconvective patterns to an external magnetic field H in a homeotropic nematic system where spatiotemporal chaos called the soft-mode turbulence (SMT) occurs. We introduce new order parameter Op, obtained directly from the amplitude spectrum of the patterns. We measure the degree of regularity of patterns under influence of H using O p and compare with the pattern ordering Mp obtained from analogy with the magnetization in 2D XY model. Our new order parameter O p is well proportional to Mp.
