LISHCHUK, S. V. (2007). Waves at surfactant-laden liquid-liquid crystal interface. Physical Review E (PRE), 76 (1), 011711.Full text not available from this repository.
A theoretical study is presented of surface waves at a monomolecular surfactant ﬁlm between an isotropic liquid and a nematic liquid crystal for the case when the surfactant ﬁlm is in the isotropic two-dimensional ﬂuid phase and induces homeotropic normal to the interface orientation of the nematic director. The dispersion relation for the surface waves is obtained, and different surface modes are analyzed with account being taken of the anchoring induced by the surfactant layer, the curvature energy of the interface, and the anisotropy of the viscoelastic coefﬁcients. The dispersion laws for capillary and dilatational surface modes retain structure similar to that in isotropic systems, but involve anisotropic viscosity coefﬁcients. Additional modes are related to relaxation of the nematic director ﬁeld due to anchoring at the interface. The results can be used to determine different properties of nematic-surfactant-isotropic interfaces from experimental data on surface light scattering.
