Optical N-plasmon: topological hydrodynamic excitations in graphene from repulsive Hall viscosity
Edge states occurring in Chern and quantum spin-Hall phases are signatures of the topological electronic band structure in two-dimensional (2D) materials. Recently, a new topological electromagnetic phase of graphene characterized by the optical N-invariant was proposed. Optical N-invariant arises f...
