Steady state Hopf mode interaction in anisotropic systems
A paradigm example of pattern formation in anisotropic extended systems is the electroconvection of nematic liquid crystals, due to its easily accessible control parameters and the variety of patterns near onset. Some of the patterns observed are oblique and normal rolls which can be stationary or traveling, and more complex structures such as worms, defects and spatiotemporal complexity, including spatiotemporal intermittency and chaos, can occur, see e.g., Dennin et al, Science 272, 1996. During electroconvection experiments on the nematic liquid crystal mixture Phase V, a mode interaction ...
