Topological Order: From Long-Range Entangled Quantum Matter to a Unified Origin of Light and Electrons

Table 1

Symmetry-breaking orders can be probed/defined through linear responses. But topological order cannot be probed/defined through linear responses. We need topological probes to define topological orders.
