| Outline of Final Research Achievements |
Physical properties of transport phenomenon of the weak turbulence in electroconvection of nematic liquid crystals have been studied. The weak turbulence occurs by the interaction between convective flow and nematic director. The statistical mechanical method such as external force response, correlation function, and Brownian motion were used to investigate the properties. As a result, the fluctuations due to the nonlinear interaction of multiple modes showed unique properties different from the thermal fluctuation targeted by the statistical mechanics so far. In addition, it was revealed that the transport phenomena change qualitatively depending on the observation scale, reflecting the coexistence of local order and global disorder in the weak turbulence.
