Real-Space Topology and Charge Order in the Haldane-Holstein Model (opens in new tab)

Author(s): Sebastião dos A. Sousa-Júnior, Julián Faúndez, Tarik P. Cysne, Richard T. Scalettar, and Rubem MondainiWe study the half-filled Haldane-Holstein model, where a paradigmatic Chern insulator is coupled to fully dynamical phonons, and provide an unbiased characterization of how retarded electron-phonon interactions destabilize Chern topology. Using determinant quantum Monte Carlo, we find that increasin…[Phys. Rev. Lett. 136, 256501] Published Tue Jun 23, 2026
