Electrically-tunable positioning of topological defects in liquid crystals by Sandford O’Neill, JJ, Salter, PS, Booth, M, Elston, S, Morris, S

“…Topological defects are a consequence of broken symmetry in ordered systems and are important for understanding a wide variety of phenomena in physics. In liquid crystals (LCs), defects exist as points of discontinuous order in the vector field that describes the average orientation of the molecules in space and are crucial for explaining the fundamental behaviour and properties of these mesophases. …”
