Figure 1 (a) Concept of a 1D space-time hopfion crystal. (b) Spin textures on x-y transverse cross-section and (c) that on selective longitudinal cross-sections through the center of a unit hopfion lattice. (d) The arrow indicator of all states of spin on a parametric sphere. (e) The isospin lines of selected spins on the equator of the parametric sphere form a torus-knot configuration. (f) All isospin lines of a hopfion lattice show a layer-by-layer torus-knot fibration configuration.
