A sweeping twist defect as a topological flagellum that drives colloid motion
Qi Xing Zhang, Claire Dore, Mojtaba Rajabi +2
Nematic liquid crystals can dramatically reconfigure under dynamic forcing, providing exciting opportunities in active matter. Here, we study a hybrid disk colloid rotated by an ex…
Scallop Theorem for Swimming in Anisotropic Fluids
Mojtaba Rajabi, Enej Caf, Qi Xing Zhang +6
In isotropic fluids like water, micrometer-scale swimmers have evolved swim strokes to translate despite their tiny size. As described by Purcell in his Scallop Theorem, reciprocal…
Effects of Photopatterning Conditions on Azimuthal Surface Anchoring Strength
Nilanthi P. Haputhanthrige, Mojtaba Rajabi, Oleg D. Lavrentovich
Spatially varying alignment of liquid crystals is essential for research and applications. One widely used method is based on the photopatterning of thin layers of azo-dye molecule…
Dielectric properties of a ferroelectric nematic material: quantitative test of the polarization-capacitance Goldstone mode
Alex Adaka, Mojtaba Rajabi, Nilanthi Haputhantrige +3
The recently discovered ferroelectric nematic (NF) liquid crystals (LC) have been reported to show an extraordinarily large value of the real part of the dielectric constant at low…
Electrically tunable total reflection of light by oblique helicoidal cholesteric
Olena S. Iadlovska, Kamal Thapa, Mojtaba Rajabi +3
An oblique helicoidal state of a cholesteric liquid crystal (ChOH) is capable of continuous change of the pitch P in response to an applied electric field. Such a structure reflect…
High order nonlinear electrophoresis in a nematic liquid crystal
Mojtaba Rajabi, Taras Turiv, Bing-Xiang Li +3
Electrophoresis is the motion of particles relative to a surrounding fluid driven by a uniform electric field. In conventional electrophoresis, the electrophoretic velocity grows l…
Dynamic control of active droplets using light-responsive chiral liquid crystal environment
Vanessa Jirón, Mojtaba Rajabi, Hao Wang +1
Microscopic active droplets are of interest since they can be used to transport matter from one point to another. The challenge is to control the trajectory. In this work, we demon…
