We present a calculation of the time-dependent structure factor based on a dynamical model which incorporates consistently the coupling of the director field with the velocity flow and also the effect of fluctuations. The appearance and development of a characteristic periodicity is described in terms of the time dependence of the maximum of the structure factor. We find a well-defined time for the appearance of the pattern and a subsequent stage of pattern development in which the characteristic periodicity tends to an asymptotic value.11 p.application/pdfeng(c) The American Physical Society, 1987Cristalls líquidsCristalls líquids nemàticsLiquid crystalsNematic liquid crystalsinfo:eu-repo/semantics/article16786info:eu-repo/semantics/openAccess
