| Research Abstract |
Technique and mechanism of controlling for spatiotemporal chaos in electroconvection of nematic liquid crystals were studied. In the controlling for sptiotemporal intermittency in the defect lattice, spatial ordered structure is reformed by spatial interaction of temporal synchronization. The soft-mode turbulence which occurs by the interaction between convection and a Nambu-Goldstone mode in orientation of the liquid crystal can be controlled by a magnetic field which suppresses fluctuations of the orientation.
