Fig. 7: The interaction of polyskyrmionomers with other solitons.

a A dimer array. b A dimer gas. c A toron interacting with dimer gases. d Numerically simulated iso-surface that depicts the 3D n(r) of a toron at \(|{n}_{z}|\)= 0.8. The iso-surface colours represent the polar and azimuthal angles of the vectorized director orientations, as defined by the coloured sphere. e A hopfion interacting with the solitonic dimers. f Numerically simulated iso-surface that depict n(r) of a hopfion at \(|{n}_{z}|\)= 0.8. Trajectories of the geometric centre in (a–c, e) are plotted versus time by means of the colour-coded scale displayed in (a). Scale bars correspond to 10 μm and f = 100 Hz.
