Complex nonlinear behavior in optically excited nematic liquid crystals.

摘要: We present a study of the passage monochromatic, linearly polarized cw laser beam through cell homeotropically aligned nematic liquid crystal at slightly oblique angle. The light is perpendicular to plane incidence. Experiments in this geometry have revealed existence complex, time-dependent dynamics director motion. model for derived from basic equations that shows both periodic and chaotic behavior different intensities as observed experiments. we derive exhibits variety complex behaviors, among them an uncommon route chaos via gluing bifurcations has not yet been any real physical system.
