Our most recent study provides that the most important effect related to the solitary wave is the flexoelectric polarization. An electric field would accumulate the liquid crystal molecules and form a locally dipole-like orientation. With an alternating current field, the flexoelectric polarization would lead to nonsingular perturbation of the director field, which looks like a butterfly. Also, bow-like structures can be induced and shotted from the butterfly, which we called bullets.
We reveal that the inducing of the nonsingular structures depends on the intensity and frequency of the electric field. And in a system with a curved director field, the solitary waves can be observed creating beside the interface of the system. Our simulation results are agreed with the phenomena in the experiment, and help us to understand them.
