Phase structure of topological insulators by lattice strong-coupling expansion
Yasufumi Araki, Taro Kimura, Akihiko Sekine +2
The effect of the strong electron correlation on the topological phase structure of 2-dimensional (2D) and 3D topological insulators is investigated, in terms of lattice gauge theo…
Phase structure of 2-dimensional topological insulators by lattice strong coupling expansion
Yasufumi Araki, Taro Kimura
The phase structure of 2-dimensional topological insulators under a sufficiently strong electron-electron interaction is investigated. The effective theory is constructed by extend…
Strong Coupling Expansion in a Correlated Three-Dimensional Topological Insulator
Akihiko Sekine, Takashi Z. Nakano, Yasufumi Araki +1
Motivated by recent studies which show that topological phases may emerge in strongly correlated electron systems, we theoretically study the strong electron correlation effect in…
