Query: Correlation-driven phase transition in a Chern insulator   The phase transition driven by electron correlations in a Chern insulator is
investigated within the dynamical mean-field theory. The Chern insulator is
described by the Haldane model and the electron correlations are incorporated
by introducing the short-range interaction between the itinerant electrons and
localized fermions. In the preservation of the inversion symmetry, the electron
correlations drive the system from the Chern insulator to a renormalized
pseudogap metal, and then to the topologically trivial Mott insulator. When the
inversion symmetry is broken, a charge ordering and a nontrivial Chern
topological invariant coexist.
