Tunneling probes can measure anyon dispersion via quasiparticle interference patterns and continuum thresholds in fractional Chern insulators.
Chiral Bloch states in rhombohedral n-layer graphene cause high-harmonic generation whose dominant order scales linearly with n, with valley splitting producing n-dependent circular dichroism.
A self-consistent continuum Hartree+U model with long-range Coulomb interactions maps the magnetic phase diagram of magic-angle twisted bilayer and trilayer graphene versus doping and twist angle.
The ghost Gutzwiller variational embedding framework recovers an effective band structure for topological phases in strongly correlated systems and reveals topologically nontrivial Hubbard bands with edge states in the interacting Bernevig-Hughes-Zhang model.
A microscopic tunneling approach is developed showing that scanning tunneling spectroscopy can distinguish commensurate and incommensurate single-q pairing states and a three-q moiré superconductor in rhombohedral graphene via broken time-reversal symmetry features and spatial Andreev conductance.
Mean-field theory on a quartic-dispersion Chern band for rhombohedral graphene yields a chiral topological superconductor that transitions to a trivial BEC at T=0; the composite-fermion version realizes a Moore-Read state.
