Topological mott insulator at quarter filling in the interacting haldane model

HIGHLIGHTS

• who: Peizhi Mai from the DepartmentUniversity of Illinois Urbana-Champaign, Urbana, Illinois, USA have published the research work: Topological Mott insulator at quarter filling in the interacting Haldane model, in the Journal: (JOURNAL) of 19/01/2023
• what: By including interactions in the topologically nontrivial Haldane model the authors show that a quarter-filled state emerges with a nonzero Chern number provided the interactions are sufficiently large. To further buttress the previous arguments that breaking this symmetry establishes a fixed point and hence the nature of the interactions, which accomplishes this is irrelevant, the authors . . .
