Topology-based crystal structure generator
WebDec 1, 2024 · Significance. Liquid crystals (LCs) are used in a number of optical devices including lasers. However, until now, only relatively simple LC structures have been employed inside laser cavities. LCs enable the self-assembly of extremely complex birefringent structures, which would be impossible to manufacture in any other way. WebMar 1, 2013 · The range of possible topological structures in liquid crystals can be widened through the use of confined volumes with prescribed boundary conditions. The first generation of such confined ...
