Applications of the Peach-Koehler Force in Liquid Crystals
Cheng Long, Jonathan V. Selinger
In solids, external stress induces the Peach-Koehler force, which drives dislocations to move. Similarly, in liquid crystals, an external angular stress creates an analogous force,…
Frank-Read Mechanism in Nematic Liquid Crystals
Cheng Long, Matthew J. Deutsch, Joseph Angelo +4
In a crystalline solid under mechanical stress, a Frank-Read source is a pinned dislocation segment that repeatedly bows and detaches, generating concentric dislocation loops. We d…
Explicit Demonstration of Geometric Frustration in Chiral Liquid Crystals
Cheng Long, Jonathan V. Selinger
Many solid materials and liquid crystals exhibit geometric frustration, meaning that they have an ideal local structure that cannot fill up space. For that reason, the global phase…
Coarse-grained theory for motion of solitons and skyrmions in liquid crystals
Cheng Long, Jonathan V. Selinger
Recent experiments have found that applied electric fields can induce motion of skyrmions in chiral nematic liquid crystals. To understand the magnitude and direction of the induce…
Geometry and mechanics of disclination lines in 3D nematic liquid crystals
Cheng Long, Xingzhou Tang, Robin L. B. Selinger +1
In 3D nematic liquid crystals, disclination lines have a range of geometric structures. Locally, they may resemble or defects in 2D nematic phases, or they may have 3…
