Topological defects of nematic liquid crystals confined in porous networks / F. Serra, K.C. Vishnubhatla, M. Buscaglia, R. Cerbino, R. Osellame, G. Cerullo, T. Bellini. - In: SOFT MATTER. - ISSN 1744-683X. - 7:22(2011), pp. 10945-10950. [10.1039/C1SM05813D]
Abstract:
We study the formation of topological defects in nematic liquid crystals confined in open bicontinuous
networks produced in glass by femtosecond laser micromachining. We obtain a careful classification of
the number and localisation of the defects as a function of the topological properties of the network.
Our findings lead to a general formula that predicts the total topological charge in open complex
networks, thus complementing the classic Stein–Gauss theorem. Our result provides a justification for
the observed multistability of nematics confined in porous networks.
