Topological invariants for interacting topological insulators: II. Breakdown of the Green's function formalism
Yuan-Yao He, Han-Qing Wu, Zi Yang Meng +1
Topological phase transitions in free fermion systems can be characterized by closing of single-particle gap and change in topological invariants. However, in the presence of elect…
Topological invariants for interacting topological insulators: I. Efficient numerical evaluation scheme and implementations
Yuan-Yao He, Han-Qing Wu, Zi Yang Meng +1
The aim of this series of two papers is to discuss topological invariants for interacting topological insulators (TIs). In the first paper (I), we provide a paradigm of efficient n…
Bona fide interaction-driven topological phase transition in correlated SPT states
Yuan-Yao He, Han-Qing Wu, Yi-Zhuang You +3
It is expected that the interplay between non-trivial band topology and strong electron correlation will lead to very rich physics. Thus a controlled study of the competition betwe…
Quantum Monte Carlo study of strange correlator in interacting topological insulators
Han-Qing Wu, Yuan-Yao He, Yi-Zhuang You +3
Distinguishing the nontrivial symmetry-protected topological (SPT) phase from the trivial insulator phase in the presence of electron-electron interaction is an urgent question to…
