摘要
We report the observation of a new light-induced spatio-temporal transition in homeotropically aligned nematic liquid crystals under the action of circularly polarized light. We believe that the competition ot synnnetric and asymmetric excitation modes is at the origin of this abrupt transition. A theoretical model explaining the main features of the observation is proposed. (C) 2002 Elsevier Science B.V. All rights reserved.
