A SPMB microsphere within a toron's double twist cylinder.
(a), A SPMB (center of mass highlighted with a green dot) embedded within the double twist cylinder of a toron (denoted by a red dot.) (b), Motional tracks of the SPMB and toron center of mass (green and red respectively) shows an orbital path around a particle/toron barycenter. (c), Simulated director field around a SPMB located at the axis of the double twist cylinder. The diameter of the 4.5 μm SPMB is roughly a quarter of the cell thickness. The director on the particle's surface is dipolar with two boojums, as visualized by the streaks. The red-to-blue color gradient encodes the out-of-plane component of the director, the blue marking the core of the double-twist cylinder.
