Abstract
We solve the complete tensor fluctuation problem of a long and straight nematic disclination line with a general winding number in the one elastic constant approximation. Focusing on the eigenmodes growing in time, we show that the disclination with strength higher than is unstable with respect to the splitting and for integer strength also to the escape—in both cases there is no metastability. Numerically we show that a moderate elastic anisotropy, e.g., as found in thermotropic liquid crystals like 5CB or MBBA, does not introduce any metastability either.
