, 2021 The tricritical and the re-entrant nematic behaviour are two of the most relevant features of the Smectic A (SmA)-to-Nematic (N) phase transition in binary mixtures of liquid crystals. Both of these concepts are studied from a theoretical and an experimental point of view for some two-component systems whose members are calamitic liquid crystals ...

Biophysical Journal, 2014 SignificanceWe propose a class of active matter, the living liquid crystal (LLC), representing motile rod-shaped bacteria placed in water-based nontoxic liquid crystal. Long-range orientational order of the liquid crystal and the swimming activity of bacteria demonstrate a strong coupling that dramatically alters individual and collective bacterial ...

Three-dimensional solitary waves with electrically tunable direction of propagation in nematics
Nature Communications, 2019 In a previous work, the authors have demonstrated the formation of localized waves in nematic liquid crystals driven by an electric field. Here they demonstrate the realization of solitary waves of (3+2)D type which can be steered along longitudinal and ...

Electro-optical switching by liquid-crystal controlled metasurfaces [PDF]
, 2013 We study the optical response of a metamaterial surface created by a lattice of split-ring resonators covered with a nematic liquid crystal and demonstrate millisecond timescale switching between electric and magnetic resonances of the metasurface.

Electrically driven three-dimensional solitary waves as director bullets in nematic liquid crystals
Nature Communications, 2018 Solitary waves which maintain their shape have many fascinating physical and mathematical properties. Here the authors observe waves trapped along three spatial dimensions in nematic liquid crystals due to an electric field and show that these director ...
