It is pointed out that the equation of motion of the nematic director under simple shear flow conforms to the driven over-damped sine-Gordon equation and has a soliton solution of amplitude pi. It has also been shown that the stationary state with the director uniformly oriented at a Leslie angle is only a metastable state and that the potential, which governs the motion of the director, has infinite numbers of stable stationary states. Therefore, the defects, appearing as a stable solitary solution, can be nucleated from a uniformly aligned flow-aligning type of nematic liquid crystal by shear flow. On the other hand, the bands with long axis parallel to the vorticity axis, appearing as an unstable-solution, can be observed as transient patterns at tow shear rate and low shear strain value, The theoretical predictions are compared with previous experimental observations."}],"citation":{"bibtex":"@article{Yang_Luo_Schmidt_Peter_2002, title={Solitons and production of defects in flow-aligning nematic liquid crystals under simple shear flow}, volume={12}, journal={Progress in Natural Science}, author={Yang, Yuliang and Luo, K.
