  text: The production of defects in flow-aligning nematic liquid crystals under simple
    shear flow is analyzed by linear stability analysis based on Leslie-Ericksen theory.
    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.
