Abstract:While the understanding of Abelian topological order is comprehensive, how to describe the internal correlation structure of non-Abelian states is still outstanding. Here, we propose a general scheme based on the many-body Chern number matrix to characterize the non-Abelian multicomponent fractional quantum Hall states at filling factions ν = 2k/(2kM + 3) (k, M ∈ Z). As a concrete example, we study the many-body ground states of two-component bosons in topological flat band models. Utilizing density-matrix ren… Show more
