Chiral π Domain Walls Composed of Twin Half-Integer Surface Disclinations in Ferroelectric Nematic Liquid Crystals
Shengzhu Yi, Zening Hong, Zhongjie Ma +7
Ferroelectric nematic liquid crystals are polar fluids characterized by microscopic orientational ordering and macroscopic spontaneous polarizations. Within these fluids, walls tha…
Line defects in nematic liquid crystals as charged superelastic rods with negative twist--stretch coupling
Shengzhu Yi, Hao Chen, Xinyu Wang +4
Topological defects are a ubiquitous phenomenon in diverse physical systems. In nematic liquid crystals (LCs), they are dynamic, physicochemically distinct, sensitive to stimuli, a…
Chiral Active Particles are Sensitive Reporter to Environmental Geometry
Chung Wing Chan, Daihui Wu, Kaiyao Qiao +4
Chiral active particles (CAPs) are self-propelling particles that break time-reversal symmetry by orbiting or spinning, leading to intriguing behaviors. Here, we examined the dynam…
Machine Eye for Defects: Machine Learning-Based Solution to Identify and Characterize Topological Defects in Textured Images of Nematic Materials
Haijie Ren, Weiqiang Wang, Wentao Tang +1
Topological defects play a key role in the structures and dynamics of liquid crystals (LCs) and other ordered systems. There is a recent interest in studying defects in different b…
