摘要: A generalized Landau-Ginzburg-de Gennes theory of cholesteric pitch in lyotropic chiral liquid crystals is presented. Using the non-critical order parameter, introduced by Toledano and Figueiredo Neto, question dependence on micellar shape addressed. This extra parameter accounts for change micelles. The predictions agree qualitatively with unique experimental observations Lopes Neto.
