![]() | Wu, Yong-Shi | General theorem relating the bulk topological number to edge states in two-dimensional insulators | We prove a general theorem on the relation between the bulk topological quantum number and the edge states in two-dimensional insulators. It is shown that whenever there is a topological order in bulk, characterized by a nonvanishing Chern number, even if it is defined for a nonconserved quantity s... | Edge states; Bulk topology; Chern number | 2006-07 |
