Structural transformations in tetravalent nematic shells induced by a magnetic field
Yoko Ishii, Ye Zhou, Kunyun He +4
The role of applied fields on the structure of liquid crystals confined to shell geometries has been studied in past theoretical work, providing strategies to produce liquid crysta…
Threading the spindle: a geometric study of chiral liquid crystal polymer microparticles
H. S. Ansell, D. S. Kim, R. D. Kamien +2
Polymeric particles are strong candidates for designing artificial materials capable of emulating the complex twisting-based functionality observed in biological systems. In this l…
Reconfigurable Flows and Defect Landscape of Confined Active Nematics
Jérôme Hardoüin, Rian Hughes, Amin Doostmohammadi +5
Using novel micro-printing techniques, we develop a versatile experimental setup that allows us to study how lateral confinement tames the active flows and defect properties of the…
Temperature-driven anchoring transitions at liquid crystal / water interfaces
Guillaume Durey, Yoko Ishii, Teresa Lopez-Leon
Controlling the anchoring of liquid crystal molecules at an interface with a water solution influences the entire organization of the underlying liquid crystal phase, which is cruc…
Bivalent defect configurations in inhomogeneous nematic shells
V. Koning, T. Lopez-Leon, A. Fernandez-Nieves +1
We present a theoretical study of the director fields and energetics of nematic liquid crystal shells with two pairs of surface defects. The pairs of defects can undergo abrupt tra…
