Elementary dislocation in a cholesteric LC

T. Ishikawa and O.D. Lavrentovich, Phys. Rev. E 59, 4752 (1999).

The dislocation profile can be properly described only
when the nonlinear term is retained. Fitting the
dislocation profile yields the elastic length K/B. Also:
Dislocations in cholesteric diffraction gratings give rise to the optical vortices in the diffracted beams.
