Abstract
The effect of surface-induced (dis)order on collective orientational fluctuations in nematic liquid crystals is studied within Landau-de Gennes theory. Close to the nematic-isotropic phase transition the corresponding spectra are characterized by soft modes, which are associated with fluctuations of the thickness of the (dis)ordered wetting layer. In this range the dynamical part of the evanescent light scattering is dominated by the soft modes.
