- We present a unified framework to systematically embed complex knotted and linked structures, beyond the torus family, into diverse topological phases, including Hopf insulators, classical spin liquids, topological semimetals, and non-Hermitian metals. Using rational maps and level sets of complex polynomials, we explicitly construct new topological models exhibiting rich and previously inaccessible textures. These topological features manifest distinctly across physical systems: emergent magnetic field lines in Hopf insulators directly reflect the rational-map topology, paralleling topological electromagnetism, while in classical spin liquids the topology is experimentally accessible via the equal-time structure factor. Our approach thus provides both a conceptual unification of previously disconnected systems and a practical toolset for realizing and detecting intricate topological textures in experiments.
