Abstract

The aim of this work is to characterize the complexity of nematic liquid crystal auto-organizing structures. The formation of these kinds of frames is due to the application of a particular electric field to the sample. Varying this control parameter, the structures evolve from very regular frames to very disorderly ones. For all these different cases we had acquired a string of data. We manage to classify these sequences, taken on the liquid crystal, according to their degree of complexity through an entropy method, the Diffusion Entropy Method.
