We create regular and tunable large-scale array of topological defects in liquid crystals by alternating electrodes with different conductivity. We study the periodicity and the regularity of the network as a function of the electrodes size.
Topological defects are one of the most conspicuous features of liquid crystals. In two dimensional nematics, they have been shown to behave effectively as particles with both, charge and orientation,...
