Artificial web of disclination lines in nematic liquid crystals

Nature Communications, 2017
Disclination lines are topological defects in molecular orientation widely found in liquid crystals. Here Wang et al. use a surface patterning technique to produce a very stable freestanding 3D array of ½ twist disclinations, which could be exploited in ...

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 ...

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 ...
