Tunable Three-Dimensional Architecture of Nematic Disclination Lines
Alvin Modin, Biswarup Ash, Kelsey Ishimoto +3
Disclinations lines play a key role in many physical processes, from the fracture of materials to the formation of the early universe. Achieving versatile control over disclination…
Nematic colloidal micro-robots as physically intelligent systems
Tianyi Yao, Žiga Kos, Yimin Luo +4
Physically intelligent micro-robotic systems exploit information embedded in micro-robots, their colloidal cargo, and their milieu to interact, assemble and form functional structu…
Tunable colloid trajectories in nematic liquid crystals near wavy walls
Yimin Luo, Daniel A. Beller, Giuseppe Boniello +2
The ability to dictate colloid motion is an important challenge in fields ranging from materials science to living systems. Here, by embedding energy landscapes in confined nematic…
Experimental realization of the "lock-and-key" mechanism in liquid crystals
Yimin Luo, Francesca Serra, Kathleen J. Stebe
The ability to control the movement and assembly of particles in liquid crystals is not only an important route to design functional materials, but also sheds light on the mechanis…
Curvature-driven, One-step Assembly of Reconfigurable Smectic Liquid Crystal "Compound Eye" Lenses
Francesca Serra, Mohamed A. Gharbi, Yimin Luo +5
Confined smectic A liquid crystals (SmA LCs) form topological defects called focal conic domains (FCDs) that focus light as gradient-index lenses. Here, we exploit surface curvatur…
Non-linear dynamics of absorption and photo-bleaching of dyes
Francesca Serra, Eugene M. Terentjev
The celebrated Lambert-Beer law of light absorption in photochromic media is only valid at low intensities of incident light and low concentration of chromophore. Here we address t…
