Photo-electrons unveil topological transitions in graphene-like systems
The topological structure of the wavefunctions of particles in periodic potentials is characterized by the Berry curvature Ω(kn) whose integral on the Brillouin zone is a topological invariant known as the Chern number. The bulk-boundary correspondence states that these numbers define the number of...
