Multipartitioning topological phases by vertex states and quantum entanglement
Multipartitioning topological phases by vertex states and quantum entanglement
We discuss multipartitions of the gapped ground states of (2+1)-dimensional topological liquids into three (or more) spatial regions that are adjacent to each other and meet at points. By considering the reduced density matrix obtained by tracing over a subset of the regions, we compute various correlation measures, such as …
