Visual Representation
To understand the concept of topological phases, let's visualize the band structure of a topological insulator. The band gap in the bulk of the material is trivial, but the edge states are protected by the topology.
By studying topological phases, scientists aim to unlock new technologies and deepen our understanding of the quantum world.
