Extended Data Fig. 5: Time-crystalline diversity from superposition of two CSTCs.
From: Space-time crystals from particle-like topological solitons

a, An orthorhombic lattice pattern generated by orthogonally superimposing polarizing optical micrograph snapshots of two CSTCs. b, An orthorhombic lattice pattern derived from space-time images of two CSTCs, where the selected area is marked in (a) with dashed rectangles. c, A monoclinic lattice pattern generated by obliquely superimposing polarizing optical micrograph snapshots of two CSTCs. d, A monoclinic lattice pattern produced from space-time images of two CSTCs, where the selected area is marked in (c) with dashed rectangles. The 2×2 white lattices in (b) and (d) correspond to the orthorhombic and monoclinic lattices, respectively. Spatial and temporal axes are labeled in each image.
