We develop a controlled theoretical framework for the topological heavy fermion model relevant to magic-angle twisted bilayer graphene, where low density conduction electrons hybri…
Quantum Geometry Driven Crystallization: A Neural-Network Variational Monte Carlo Study
Agnes Valenti, Yaar Vituri, Yubo Yang +7
Wigner crystals are a paradigmatic form of interaction driven electronic order. A key open question is how Berry curvature and, more generally, quantum geometry reshape crystalliza…
The Interacting Energy Bands of Magic Angle Twisted Bilayer Graphene Revealed by the Quantum Twisting Microscope
J. Xiao, A. Inbar, J. Birkbeck +6
Electron interactions in quantum materials fundamentally shape their energy bands and, with them, the material's most intriguing quantum phases. Magic angle twisted bilayer graphen…
