  Dynamic simulations of the isotropic-nematic phase transformation of liquid
crystal droplets under homeotropic anchoring are found to predict chiral
symmetry-breaking dynamics. These observations occur when using material
parameters for pentyl-cyanobiphenyl (5CB) but not under the single elastic
constant approximation of this material, frequently used in simulation. The
twisting dynamic process occurs during the relaxation of the domain from an
unstable radial texture to a stable uniform texture and involves simultaneous
defect loop motion and twisting of the bulk nematic texture.
