Research Abstract |
In order to establish the statistical physics for dissipative structures, fluctuations of spatiotemporal chaos in electroconvective systems of nematic liquid crystals were investigated from the statisticalmechanical viewpoint. Spatiotemporal chaos has stratified dual structures which consist of local ordered structures and global disordered ones. By the measurements of diffusion phenomena and temporal correlation function for pattern fluctuations, it was clarified that spatiotemporal chaos shows dual structures in the spatiotemporal scale change also in the statisticalmechanical properties
