Sublattice-selective interlayer hybridizations in twisted bipartite lattice heterobilayers generate tunable zero-energy flat bands possessing finite Berry curvature and Chern-insulator-scale quantum metric.
A new protocol for layer-resolved transport measurements that extracts anyon statistics from charge distribution across layers in multi-component topological states.
A variational generalized Landau-level mapping shows the first moiré valence band supports Jain-sequence Abelian states while the Hartree-Fock-renormalized second band hosts a non-Abelian Moore-Read state at filling 5/2 for twist angle 2.45°.
Doping the Kane-Mele-Hubbard model at filling ν=1 induces quantum anomalous Hall crystals with skyrmion spin textures and topological domain walls hosting chiral modes.
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.
False vacuum decay in flat-band ferromagnets shows that quantum geometry governs magnetization bubble dynamics in metals and allows dynamical access to chiral edge modes in quantum Hall ferromagnets.
Pressure tunes band flatness and geometry in tMoTe2 to control FCI and GWC phases and their topological transitions at fractional fillings.
