Numerical DMRG calculations show that gate screening binds like-charged anyons into molecules in Laughlin, Jain, and anti-Pfaffian fractional quantum Hall states.
Lattice relaxation strain fields flatten and isolate a |C|=1 Chern band in rhombohedral graphene-hBN heterostructures under Hartree-Fock interactions.
Band inversion between orbital doublet and isolated orbital creates interaction-shielded QBCP gapped by intrinsic SOC, enabling robust QAH in proposed MNX2 monolayers.
A symmetry indicator framework predicts the Z2 or Chern number of superlattice minibands from the parent material's properties alone, assuming weak potential but valid if gaps stay open.
Calculates anomalous Hall conductivity σ_xy in rhombohedral graphene with weak dense Gaussian impurities and strong sparse impurities by summing intrinsic, side-jump, Gaussian and non-Gaussian skew-scattering diagrams in the Kubo-Streda formalism, plus perturbative warping.
Systematic variation of interlayer couplings and hBN potentials in TBG/hBN reveals enriched Chern number phase diagrams with states of C=3,4,5 linked to specific band inversions.
