摘要:
We predict orientational transitions in a nematic cell with co-directed and reversed orientations of easy axes on the aligning surfaces. Aside from aforwarddirector distribution there can exist thereversedistributions with zero and π/2 polar director angle at some point in the cell bulk. In the Rapini approach for the surface free energy these distributions can be unstable and transition two the forward distribution can occur. Dimensionless parameters, controlling the director distribution are the easy axis angle and an anchoring strength parameterWL/K.
