Topological zero modes and bounded modes at smooth domain walls: Exact solutions and dualities
Pasquale Marra, Angela Nigro
Topology describes global quantities invariant under continuous deformations, such as the number of elementary excitations at a phase boundary, without detailing specifics. Convers…
