- MIT/Harvard Nature (5 Feb 2025 note): first direct superfluid-stiffness measurement in magic-angle graphene; ~10× conventional expectation in that report; temperature dependence read as quantum-geometry.
- Nature 637, 1084 (22 Jan 2025). Moiré-driven topological electronic crystals in twisted bilayer–trilayer graphene; ν = 1/4 with integer quantum anomalous Hall; Chern number switchable +1/−1.
