Dynamics of nematic elastomers
Olaf Stenull, T. C. Lubensky
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…
Microrheology, stress fluctuations and active behavior of living cells
A. W. C. Lau, B. D. Hoffman, A. Davies +2
We report the first measurements of the intrinsic strain fluctuations of living cells using a recently-developed tracer correlation technique along with a theoretical framework for…
Anomalous elasticity of nematic and critically soft elastomers
Olaf Stenull, T. C. Lubensky
Uniaxial elastomers are characterized by five elastic constants. If their elastic modulus C_5 describing the energy of shear strains in planes containing the anisotropy axis vanish…
The Structure of TGB Phases
Arindam Kundagrami, T. C. Lubensky
We study the transition from the cholesteric phase to two TGB phases near the upper critical twist : the Renn-Lubensky TGB phase, with layer normal rotating in a pl…
Fluctuating Nematic Elastomer Membranes: a New Universality Class
Xiangjun Xing, Ranjan Mukhopadhyay, T. C. Lubensky +1
We study the flat phase of nematic elastomer membranes with rotational symmetry spontaneously broken by in-plane nematic order. Such state is characterized by a vanishing elastic m…
