Experimental synchronization of spatiotemporal disorder — •Katharina Havermann, Björn Gütlich, and Cornelia Denz — Institut für Angewandte Physik, Westfälische Wilhelms-Universität, Corrensstr. 2, 48149 Münster, Germany

In the last years, the experimental investigation of synchronization of temporal chaotic systems has received increased attention. In this field synchronization of chaos in space and time is a rather new and hardly explored topic with great potential for new phenomena. An interesting model system showing various types of spatiotemporal dynamic is the liquid crystal light valve (LCLV) single feedback system. Subsequently to first successful experiments of synchronization of unidirectional coupled systems the role of spatial inhomogeneities is analyzed in detail. The degree of synchronization is measured for different coupling strengths. The whole range of spontaneous structures of the nonlinear optical system with focus on spatiotemporal disordered states is considered. For analysis cross-correlation functions and mutual information are used.
