Photonic gaps in cholesteric elastomers under deformation
, 2004 Cholesteric liquid crystal elastomers have interesting and potentially very useful photonic properties. In an ideal monodomain configuration of these materials, one finds a Bragg-reflection of light in a narrow wavelength range and a particular circular ...

Magnetorheological effect in elastomers containing uniaxial ferromagnetic particles
, 2020 The description of the collective magnetorheological effect induced by magnetic field in magnetoactive elastomers is proposed. The condition of consistency is used between magnetic and mechanic momenta of forces exerted on magnetically uniaxial ...

Isotropic-Nematic Transition in Liquid-Crystalline Elastomers
, 2002 In liquid-crystalline elastomers, the nematic order parameter and the induced strain vary smoothly across the isotropic-nematic transition, without the expected first-order discontinuity.

Smectic elastomer membranes [PDF]
Physical Review E, 2007 We present a model for smectic elastomer membranes which includes elastic and liquid crystalline degrees of freedom. Based on our model, we determined the qualitative phase diagram of a smectic elastomer membrane using mean-field theory. This phase diagram is found to comprise five phases, viz.

UV-isomerisation in nematic elastomers as a route to photo-mechanical transducer
, 2002 The macroscopic shape of liquid crystalline elastomers strongly depends on the order parameter of the mesogenic groups. This order can be manipulated if photoisomerisable groups, e.g. containing N=N bonds, are introduced into the material.
