Dynamics of nematic elastomers
arXiv:cond-mat/0311464 · doi:10.1103/PhysRevE.69.051801
Abstract
We study the low-frequency, long-wavelength dynamics of soft and semi-soft nematic elastomers using two different but related dynamic theories. Our first formulation describes the pure hydrodynamic behavior of nematic elastomers in which the nematic director has relaxed to its equilibrium value in the presence of strain. We find that the sound-modes structure for soft elastomers is identical to that of columnar liquid crystals. Our second formulation generalizes the derivation of the equations of nematohydrodynamics by the Harvard group to nematic elastomers. It treats the director explicitly and describes slow modes beyond the hydrodynamic limit.
