The simulation reproduces the observed relaxation from the homeotropic state to the long pitch transient planar state. The simulation agrees with the suggestion that the transient planar-planar transition occurs via a three-dimensional Helfrich-type deformation without the introduction of defect cores. On the basis of this understanding, we suggest improvements for increasing the speed of these transitions.Read More
