Ideal Chern bands are believed to be crucial for realizing anomalous fractional quantum Hall states in moiré materials. Here, the authors demonstrate that in an ideal Chern band even the celebrated Laughlin wave-function at filling 1/3 does not always describe a gapped fractional quantum Hall state, but can also describe a novel exotic gapless state that does not spontaneously break any symmetry. This state displays power-law correlations with continuously tunable exponents and quasiparticles with an unquantized continuously varying electric charge.

The hard-core Fermi-Hubbard model displays a massive spin degeneracy at half-filling: superexchange is forbidden in the hard-core limit, so all spin configurations have the same energy. Introducing a single hole, whose kinetic energy depends on the spin state, leads to magnetic ordering. This ordering is lattice dependent. The authors study here how it evolves as one interpolates between a square and triangular lattice, which can be explored using optical lattices. Using perturbative and variational arguments, they identify a phase transition between a ferromagnet and a spin-spiral state.

Motivated by correlated phases observed in moiré transition metal dichalcogenide experiments, the authors study here how Coulomb interactions are modified and how they can drive many-body instabilities. Using a Landau level description, they show that interactions acquire a spin-dependent structure that can be systematically characterized by generalized Haldane pseudopotentials. They find that Landau level mixing can destabilize the Chern insulating state at integer filling when interactions become comparable to kinetic energy, providing an experimentally relevant mechanism for the breakdown of Chern insulators in moiré materials.
