Nonlinear curvature elasticity of nematic liquid crystals
I. Lelidis, G. Barbero
The nonlinear elastic properties of nematic liquid crystals have acquired new interest with the recent experimental observation of bulk modulated nematic phases which are composed…
Fourth order nematic elasticity and modulated nematic phases: a poor man's approach
G. Barbero, I. Lelidis
We propose an extension of Frank-Oseen's elastic energy for bulk nematic liquid crystals which is based on the hypothesis that the fundamental deformations allowed in nematic liqui…
Unwinding of the twist-bend nematic structure under an external field
Rafael Soares Zola, Giovanni Barbero, Ioannis Lelids +2
The recently discovered twist-bend nematic phase, , is a non-uniform equilibrium nematic phase that presents a spontaneous bend with a precession of the nematic directo…
Temperature dependence of the nematic anchoring energy:mean field analysis
G. Barbero, A. K. Zvezdin
In the mean field approximation, we evaluate the temperature dependence of the anchoring energy strength of a nematic liquid crystal in contact with a solid substrate due to therma…
